Annotating with Hypothesis

Hypothesis is a free online tool designed to allow for collaborative annotation across the web. This guide will walk you through using Hypothesis with the Chrome extension. To use the bookmarklet in another browser, please refer to the hypothesis user guide for step-by-step instructions.

It can be used to annotate web pages, PDFs and EPUB files. You can annotate documents and pages publicly, privately, or within a group.

To get started with Hypothesis you'll need to:

• Create an account. 
• Install the Chrome extension or the Hypothesis Bookmarklet if you are using a browser other than Chrome. 
• Start annotating!

What makes Hypothesis different than other tools is that you can annotate PDFs as well as web pages. It also allows for group and collaborative annotation. 

• Create a Hypothesis Account
• Chrome Extension
• Hypothesis User Guide

Opening Web Pages and PDFs

Navigate to the web page or pdf in your browser. 

Next, select the Hypothesis icon located in the right corner of your Chrome browser if it is not already active.

 An inactive icon will appear as light gray, and if it is ready to use it will be black. If you have not used Hypothesis for a while you may need to log in to activate the program.

Once Hypothesis is active on a page you can start annotating. You can highlight text, add annotation, add a note for the whole page, share the page with others, and reply to other comments on the page. You may have to click the toggle arrow to see options, comments, and notes.

Adding Annotation and Highlighting Text

To highlight or add annotation for certain text, simply select the text and the highlight and annotation icons will appear.

To create a note for the entire page, select the note icon that appears on the Hypothesis menu on the right side of the screen. You can also toggle highlighted text on and off using the eye icon.

Formatting Annotation

Once you have selected text to annotate, an annotation box will appear in the menu on the right. The annotation section allows you to perform minor formatting of text such as bold, italics, quoted text, lists, links, and even mathematical notation that is LaTex supported.

There is also an option to add web links and links to online images and videos. Images will appear and videos will play right in the annotation section of the page. 

Adding Tags

You may also add tags to your annotation to better organize your idea and thoughts, and categorize content. To learn more about tags and how they can be used to enhance collaboration and search, please see the Using Tags Tutorial .

Public, Private, and Private Group Annotation

Annotations, notes and highlights can be made public, private or shared within a specific group. All annotation setting default to public unless you choose another option. Public annotations can be seen by anyone who visits the webpage or pdf and has Hypothesis enabled.

Switching from Public to "Only Me"

If you would like to make notes private where only you can see them, be sure to select the Only Me  option in the annotation box.

Once you have selected this option, all other annotations, highlights and notes will default to private on the page and be shown with a lock icon next to your name. To switch back select the Public option.

Private Groups

To share annotations with a group you have already created or have been invited to, select the down arrow next to Public  in the Hypothesis menu. Here you will see any private groups you belong to as well as an option to create a new private group. Selecting a group will allow you to annotate and have only the members belonging to the group view and respond to your comments, highlights and notes. 

To create a new group, select the + New Private Group option. From here you will be taken to a new screen where you will be asked to name the group. Click the Create group button to create the new private group.

Once the group is created, you will be given a link to share to invite new members to the group.

Annotating a Locally-Saved PDF 

To annotate a saved pdf in Hypothesis, open it in your browser. Once it is open in your browser activate Hypothesis to start annotating. The pdf must have selectable text in order for Hypothesis to work. If you have issues with this feature, consult the annotating locally saved pdfs tutorial .

Web annotation tool Hypothesis hits a milestone

• Rina Shaikh-Lesko 0

The team behind Hypothesis, an open-source software tool that allows people to annotate web pages, announced in March that its users had collectively posted more than 5 million comments across the scholarly web since the tool was launched in 2011. That’s up from about 220,000 total comments in 2015 (see ‘Comment counts’). The company has grown from 26,000 registered users to 215,000 over the same period.

“Five million annotations is a major milestone for us, and something we’ve worked hard to achieve,” says Hypothesis founder, Dan Whaley, who is based in San Francisco, California.

Source: Hypothesis

Hypothesis is one of a handful of tools — others include A.nnotate, Diigo, PaperHive and Remarq — that allow users to mark up and comment on any web page or online PDF, and to see annotations made by others. Hypothesis focuses on the scientific literature, and has, over the past few years, partnered with publishers, societies and educational institutes, including the journal eLife , the American Geophysical Union, the American Society of Plant Biologists and Cambridge University Press, to integrate that functionality into article pages and editorial processes. Working with eLife , for example, the service built tools to allow staff to moderate comments, and to track and authenticate users through ORCID — a digital identifier for academic authors. The journal’s readers have used the annotation tool to note minor errors and to flag up other papers that agree or disagree with conclusions. And editorial staff have used it to contribute to the dialogue. In the 15 months since eLife introduced the system, more than 6,000 annotations have been posted on nearly 2,000 documents, although about half of those were made by eLife ’s automated curation assistant, SciBot.

“I don’t think the quality of the dialogue in [the previous commenting system] was ever as constructive or as good as it is within the Hypothesis ecosystem,” says Giuliano Maciocci, head of product and user experience at eLife in Cambridge, UK. That, he says, is probably because annotations are positioned on top or next to the text to which they refer, instead of at the bottom of the page as they are in conventional commenting systems.

Some publishers have integrated annotations into their peer-review processes. In the American Geophysical Union’s system, for instance, comments can be organized by reviewer or editor, and by importance. Reviewers can see only their own comments, whereas editors can see all comments from reviewers and manuscript authors.

And some publishers are taking advantage of the tool’s enhanced group feature, which allows users to create groups that are open (available to all users), private (anyone can read, but only invited members can annotate) or restricted (only invited members can see or add annotations). Last December, the American Society of Plant Biologists launched an open group for annotations on its journal Plant Cell ; it has logged almost 30 comments.

Hypothesis is accessed using a Chrome extension, a bookmarklet, or the via.hypothes.is proxy server. In February 2017, the World Wide Web Consortium, or W3C, the international standards body for the web, formally recommended a web-annotation standard that allows developers to make annotation a native feature of their browsers. So far, none has done so.

Collaborative Annotation with Hypothesis

• Peer Review with GitHub Tickets
• Video Annotation/Analysis with the Kaltura Media Player
• Replacing Book Discussions
• Critical Organization with Zotero

This could be helpful as a replacement for class discussion about any text-based media in HTML or PDF format online. Hypothesis allows users to create “groups” for annotation. Students would be able to view each other’s annotations and respond, which could be useful as a surrogate for class discussion of a text

To foster asynchronous communication about a text by annotating passages, replying to each other’s commentary, and providing overall “page notes” with tags. Annotation tools like hypothesis encourage students to engage more directly with the text by annotating specific passages, rather than creating de-contextualized discussion boards in Canvas.

• Instructor should create an account at https://web.hypothes.is/start/ . 
• When logged in, click on the “Groups” menu link in the upper right-hand corner of your profile page. Select “create new group” at the end of the dropdown.
• Name and provide a description for the group in the provided text entry boxes
• Copy the link under “Invite New Members” to share with your students
• Have students create an account at https://web.hypothes.is/start/.
• For students using Google Chrome as their browser, have them install the Chrome extension: https://chrome.google.com/webstore/detail/hypothesis-web-pdf-annota/bjfhmglciegochdpefhhlphglcehbmek   
• For students using other browsers, have them bookmark the Bookmarklet Link found at https://web.hypothes.is/start/ . 
• If using Chrome : Click on the Hypothesis icon in their plugins menu (upper right hand corner of the browser). This will bring up Hypothesis on the right side of the browser 
• If using another browser : click on the Hypothesis Bookmarklet, which will bring up Hypothesis on the right side of the browser.
• Ensure that students click on the dropdown that says “Public” and that they select the group associated with your class (they will only see this if they are logged in in the bookmarklet/plugin).
• Once the group is selected, students can highlight text and select the pencil icon, which will give them the ability to annotate the selected text. Students can also reply to each other’s annotations in the hypothesis sidebar

Notes on Hypothesis

• Hypothesis is free and open source, which means that students do not need to pay to use it. 
• Hypothesis allows users to create highlights that are only visible to them, for their personal use.
• Hypothesis comments allow users to insert formulae using LaTeX, so it can be used in the context of STEM classes as a means of practicing this formatting language

Reading notes in Hypothesis

When you open up the app, you’ll immediately have several options to add your social layer to the internet.

There are several options that I use regularly in the initial box that pops up. Moving counter-clockwise from the top right corner:

• Use the user icon to sign out, modify my account settings, or review my public annotations. My public annotations are also available at  https://hypothes.is/stream?q=user:wiobyrne . To go directly to your annotations stream substitute my username (wiobyrne) for the username you created.
• Click the share icon to share the page and automatically add the prefix I shared earlier to allow others to use hypothes.is with you.
• Click the “Public” link to view and create annotations publicly online…or create your own private group. A private group is helpful to protect students or your information.
• Click the icon that looks like an eye to hide/reveal highlights and annotations from others on the page.
• Use the icon that looks like a document to create a note for the entire page, as opposed to individual sections, lines or words.

From this point you can also review comments already public on the page. You’ll be surprised at what is already out there online. In the graphic below I review the information contained in one note found on a webpage using Hypothesis.

• In the middle of the note, in italics, you’ll find the text they annotated or highlighted from the original source.
• On the top left of the next, in bold, you’ll find the name of the user that created the note. You can click on their name to see their public stream of notes in hypothes.is.
• Under the selected text, you’ll find the comment made by the user about the selected text.
• Beneath the comment are the tags used to identify the note. Tags are helpful ways to connect your notes with your community. You can click on the tag to see what others are sharing on that topic.
• In the bottom right corner you’ll find an icon that allows you to reply to the note and another icon to share this note. Sharing is a powerful way to tweet, share, or cite this individual note from the website.

Creating notes in Hypothesis

To begin to add your own ideas to the webpage, you start by reviewing the notes already left behind by others.

Highlight will highlight the text, and leave a note in the panel to the far right indicating that you marked up the text.

Please do not forget to add tags. Tags are like categories or themes for the text, or note you’re leaving. You can have multiple tags for each note, so don’t feel restricted. I use tags to identify research topics or groups that might be interested in that specific content.

Getting started with Hypothesis

Hopefully by this point you’ve got a good idea of how to get hypothes.is up and running in your web browser. Now it is your opportunity to get involved in the discussion and create a social layer of annotation on the web as you research online. If needed, you can review the video walkthrough I created for this tool.

You might also want to review the quick start guide  and the annotation tips for students provided by Hypothesis.

Re: configuring Hypothesis for my course

My students keep telling me that they see a message on their end saying that they are not configured to use hypothesis within my asynchronous online writing course. The hypothesis content in my course was uploaded by a tech expert at my institution, not by myself. My students cannot perform the hypothesis related work for the course because they do not appear to have access to it. How can this be addressed? How and where am I able to grade my students' submitted Hypothesis assignments? Thanks, Dr. Matt Hodgman (Stevenson University)

Very Confusing

I do not know how to navigate around your website its not giving me straight forward answers on how to download or what's the next steps in getting to the right answer with your software. I did sign up for hypothesis but it is very confusing to me on how to use it and what I am going to need it for.

I know this is going to sound silly but how do I actually use this? .

I right-click on something I want to highlight but I see no option to do anything with the highlighted text. I am signed in to the extension. A step-by-step guide would be useful as I don't see any instructions. Like, what buttons do I hit to do what. Where does the information go when I highlight it and how do I access it?

Notifications do not work

We use Hypothesis extensively for reviewing content on beta sites. It is super-useful. The only pain is that we need to inform the writer after we add comments to look at the comments. The notifications only work when someone replies to the comments. Is there a fix or setting to let the author notify when a comment is added?

Chromium Blog

Introducing shared memory versioning to improve slow interactions.

On the Chrome team, we believe it’s not sufficient to be fast most of the time, we have to be fast all of the time. Today’s The Fast and the Curious post explores how we contributed to Core Web Vitals by surveying the field data of Chrome responding to user interactions across all websites, ultimately improving performance of the web.

As billions of people turn to the web to get things done every day, the browser becomes more responsible for hosting a multitude of apps at once, resource contention becomes a challenge. The multi-process Chrome browser contends for multiple resources: CPU and memory of course, but also its own queues of work between its internal services (in this article, the network service).

This is why we’ve been focused on identifying and fixing slow interactions from Chrome users’ field data, which is the authoritative source when it comes to real user experiences. We gather this field data by recording anonymized Perfetto traces on Chrome Canary, and report them using a privacy-preserving filter.

When looking at field data of slow interactions, one particular cause caught our attention: recurring synchronous calls to fetch the current site’s cookies from the network service.

Let’s dive into some history.

Cookies under an evolving web

Cookies have been part of the web platform since the very beginning. They are commonly created like this:

And later retrieved like this:

Its implementation was simple in single-process browsers, which kept the cookie jar in memory.

Over time, browsers became multi-process, and the process hosting the cookie jar became responsible for answering more and more queries. Because the Web Spec requires Javascript to fetch cookies synchronously, however, answering each document.cookie query is a blocking operation.

The operation itself is very fast, so this approach was generally fine, but under heavy load scenarios where multiple websites are requesting cookies (and other resources) from the network service, the queue of requests could get backed up.

We discovered through field traces of slow interactions that some websites were triggering inefficient scenarios with cookies being fetched multiple times in a row. We landed additional metrics to measure how often a GetCookieString() IPC was redundant (same value returned as last time) across all navigations. We were astonished to discover that 87% of cookie accesses were redundant and that, in some cases, this could happen hundreds of times per second.

The simple design of document.cookie was backfiring as JavaScript on the web was using it like a local value when it was really a remote lookup. Was this a classic computer science case of caching?! Not so fast!

The web spec allows collaborating domains to modify each other’s cookies. Hence, a simple cache per renderer process didn’t work, as it would have prevented writes from propagating between such sites (causing stale cookies and, for example, unsynchronized carts in ecommerce applications).

A new paradigm: Shared Memory Versioning

We solved this with a new paradigm which we called Shared Memory Versioning . The idea is that each value of document.cookie is now paired with a monotonically increasing version. Each renderer caches its last read of document.cookie alongside that version. The network service hosts the version of each document.cookie in shared memory. Renderers can thus tell whether they have the latest version without having to send an inter-process query to the network service.

This reduced cookie-related inter-process messages by 80% and made document.cookie accesses 60% faster 🥳.

Hypothesis testing

Improving an algorithm is nice, but what we ultimately care about is whether that improvement results in improving slow interactions for users. In other words, we need to test the hypothesis that stalled cookie queries were a significant cause of slow interactions.

To achieve this, we used Chrome’s A/B testing framework to study the effect and determined that it, combined with other improvements to reduce resource contention, improved the slowest interactions by approximately 5% on all platforms. This further resulted in more websites passing Core Web Vitals 🥳. All of this adds up to a more seamless web for users.

Timeline of the weighted average of the slowest interactions across the web on Chrome as this was released to 1% (Nov), 50% (Dec), and then all users (Feb).

Google chrome’s plan to limit ad blocking extensions kicks off next week, chrome's manifest v3 transition is here. first up are warnings for any v2 extensions..

Ron Amadeo - May 31, 2024 6:08 pm UTC

Google Chrome will be shutting down its older, more capable extension system, Manifest V2, in favor of exclusively using the more limited Manifest V3. The deeply controversial Manifest V3 system was announced in 2019, and the full switch has been delayed a million times, but now Google says it's really going to make the transition: As previously announced , the phase-out of older Chrome extensions is starting next week.

Google Chrome has been working toward a plan for a new, more limited extension system for a while now. Google says it created "Manifest V3" extensions with the goal of "improving the security, privacy, performance, and trustworthiness of the extension ecosystem."

Other groups don't agree with Google's description, like the Electronic Frontier Foundation (EFF), which called Manifest V3 " deceitful and threatening " back when it was first announced in 2019, saying the new system "will restrict the capabilities of web extensions—especially those that are designed to monitor, modify, and compute alongside the conversation your browser has with the websites you visit." It has a whole article out detailing how Manifest V3 won't help security.

Further Reading

A big source of skepticism around Manifest V3 is limitations around "content filtering," aka the APIs ad blockers and anti-tracking extensions use to fight ad companies like Google . Google claims the goal of Manifest V3 is to improve "the security, privacy, performance, and trustworthiness," and a Google spokesperson points to this blog post , which claims that the more limited filtering system will prevent extensions from seeing  "sensitive data" on websites. It also claims there's a performance benefit to using the new filtering system. As Kewisch said, the primary goal of malicious extensions is to spy on users and slurp up data, which has nothing to do with content filtering. This is all happening while Google makes about 77 percent of its revenue from advertising, is building an ad system directly into Chrome , and Google properties like YouTube are making aggressive moves against ad blockers.

The initial version of Manifest V3 was detailed in 2019, and since then, Google has gone back and forth with the extension community and made some concessions. Google says it raised the number of filtering rulesets allowed by Manifest V3, which should help ad blockers. One contentious point has been around updating filter lists, Manifest V3 bans "remotely-hosted code," but this is typically how ad blockers updated their filter lists. In an end-of-2023 interview with Ghostery’s director of product and engineering Krzysztof Modras, Engadget wrote "Modras said that under Manifest V3, whenever an ad blocker wants to update its blocklist—again, something they may need to do multiple times a day—it will have to release a full update and undergo a review "which can take anywhere between [a] few hours to even a few weeks." In the cat-and-mouse game of ad blockers, you can imagine how this could let YouTube change the ad system instantly, while any counterpunches from ad blockers could be delayed by weeks. Google now says it's possible for extensions to skip the reviews process for "safe" rule set changes.

In a comment to The Verge last year, the senior staff technologist at the EFF, Alexei Miagkov, summed up Google's public negotiations with the extension community well, saying, "These are helpful changes, but they are tweaks to a limited-by-design system. The big problem remains the same: if extensions can’t innovate, users lose and trackers win... We now all depend on Google to keep evolving the API to keep up with advertisers and trackers."

Google says, "over 85% of actively maintained extensions in the Chrome Web Store are running Manifest V3, and the top content filtering extensions all have Manifest V3 versions available." The company doesn't mention that the most popular ad blocker's Manifest V3 version is "uBlock Origin Lite," with the "Lite" indicating that it is inferior to the Manifest V2 version.

As for how this phase out is actually going to go, Google says next week the beta versions of Chrome will start seeing warning banners on the extensions page for any Manifest V2 extensions they have installed. V2 extensions will also lose their "featured" status in the Chrome extension store. Google says extensions will start to be disabled in "the coming months." For a short period, users will be able to turn them back on if they visit the extension page, but Google says that "over time, this toggle will go away as well." At that point you can either go hunting through the Chrome Store for alternatives or switch to Firefox.

How-To Geek

Google chrome is ready to kill manifest v2 browser extensions.

Google says "over 85% of actively maintained extensions" have migrated.

Google introduced a new standard for Chrome browser extensions, Manifest V3, back in 2021. Now, Google is finally saying goodbye to the older Manifest V2 standard, potentially leaving many extensions behind.

Google said last year that the phase-out period for Manifest V2 extensions would start around June 2024, and the company is sticking to that schedule. Starting on June 3, 2024, in the Chrome Beta, Dev, and Canary channels, older Manifest V2 extensions will display a warning about being unsupported. Over the next few months, those extensions will be fully turned off, and then eventually removed from the Chrome Web Store.

The company’s blog post explained, “Like any big launches, all these changes will begin in pre-stable channel builds of Chrome first – Chrome Beta, Dev, and Canary. The changes will be rolled out over the coming months to Chrome Stable, with the goal of completing the transition by the beginning of next year. Enterprises using the ExtensionManifestV2Availability policy will be exempt from any browser changes until June 2025.”

Manifest V3 is the latest software platform for Chrome extensions, intended to make extensions faster and more secure. The change has been controversial due to Google's removal of the webRequest API, which is used by content blocker extensions to filter out network traffic. The API was replaced with declarativeNetRequests , which was initially far more limited (thus the controversy), but Google has made several upgrades over the past two years and fixed most of its issues. Most content blocker extensions now have Manifest V3 versions available.

Google says that “over 85% of actively maintained extensions” in the Chrome Web Store are already updated to Manifest V3. That number will likely go up a bit over the next month or two, as extension developers rush out updated versions before the clock runs out. You can check your own extensions by opening chrome://extensions-internals in Chrome and searching for “manifest_version” on the page.

Microsoft Edge is based on Chrome and uses many of the same extensions, but Microsoft has not yet confirmed when Manifest V2 extensions will be kicked from Edge. Mozilla Firefox uses a different extension architecture with changes to Manifest V3, and it doesn’t have plans right now to remove Manifest V2 extensions.

Google will roll out Chrome’s new extension spec next week

Google’s transition to manifest v3 has been criticized for its potential impact on ad blockers..

Share this story

Google is making way for Manifest V3, the Chrome extension specification that could change the way ad blockers work. The company says it will begin phasing out the old system on the Chrome Beta, Dev, and Canary channels starting on June 3rd.

If you’re on any of these channels, you may see a warning message on your extension management page that says Google will soon end support for extensions running on Manifest V2. The extensions will still work, but Google says it will disable them on your browser in the “coming months” before removing the ability to use them completely. The stable version of Chrome will eventually get these changes, with a full rollout set for the beginning of 2025.

What’s a manifest?

A manifest tells the browser all sorts of information about an extension, from its name and version number to which permissions it’ll use and what versions of a browser it’ll run on. New versions of the Manifest file format change which features extensions have access to. For example, Manifest V3 in Chrome no longer allows a developer to load code from a remote server.

Google’s long-delayed transition to Manifest V3 has faced pushback over concerns it could limit the effectiveness of ad blockers. However, Google has since attempted to address developers’ main concerns by adding support for user scripts and increasing the number of rulesets for the declarativeNetRequest API  used by ad blocking extensions. According to Google, Manifest V3 will help improve the security of extensions, as it removes support for remotely hosted code.

Google says 85 percent of “actively maintained” extensions in the Chrome Web Store have already created Manifest V3 versions, including some of the most popular ad blockers, like AdBlock, Adblock Plus, uBlock, and AdGuard.

Google to push ahead with Chrome's ad-blocker extension overhaul in earnest

Starting monday, users will gradually be warned the end is near.

On Monday, some people using Beta, Dev, and Canary builds of Google Chrome will be presented with a warning when they access their browser's extension management page – located at chrome://extensions .

The banner will say that legacy Manifest V2 browser extensions will stop working soon.

Those extensions include ad-blockers and other content filters that rely on the Manifest V2 API. And though leading ad-blocking extensions more or less support Manifest V2's successor, conveniently named Manifest V3, there is still some argument that these filters will be disadvantaged under version 3 when they are no longer allowed to use version 2.

In any case, users are going to be warned that V2 is on the way out.

"This will be followed gradually in the coming months by the disabling of those extensions," said David Li, product manager for Chrome Extensions, in a blog post published Thursday.

"Users will be directed to the Chrome Web Store, where they will be recommended Manifest V3 alternatives for their disabled extension. For a short time after the extensions are disabled, users will still be able to turn their Manifest V2 extensions back on, but over time, this toggle will go away as well."

The manifest file for a browser extension is where developers declare its capabilities via the Chrome Extension APIs .

The transition from Manifest V2 to Manifest V3 has been underway for at least five years. It makes new APIs available to browser extensions and removes old ones. The most salient of these is the blocking version of the webRequest API, which is used to intercept and alter network traffic prior to display. Under Manifest V2, it's what extension developers use to stop adverts, trackers, and other content appearing on pages, and prevent certain scripts from running.

The new MV3 architecture reflects Google's avowed desire to make browser extensions more performant, private, and secure. But the internet giant's attempt to do so has been bitterly contested by makers of privacy-protecting and content-blocking extensions, who have argued that the Chocolate Factory's new software architecture will lead to less effective privacy and content-filtering extensions.

As a result of this multi-year tussle and concessions Google has made to frustrated extension developers, the current version of MV3 is generally perceived to be better than initially proposed, but hasn't entirely addressed developer concerns or provided functionality that's equivalent to what's being removed.

Li acknowledged the issue by noting the ways in which Google has been responsive, by adding support for user scripts, for offscreen documents that have access to the DOM API, and by increasing the number of rulesets in the declarativeNetRequest API (the replacement for webRequest ) to 330,000 static rules and 30,000 dynamics ones. Those rules can be used by ad-blockers to weed out adverts and other stuff for users.

Manifest V3 is now supported to varying degrees by other browsers, such as Edge, Firefox, and Safari. And by the beginning of 2025, when the API changes have been available for some time in the Chrome Stable channel, Manifest V2 extensions will stop working.

Enterprises using the ExtensionManifestV2Availability policy will be spared until June 2025.

According to Li, more than 85 percent of actively maintained extensions in the Chrome Web Store support Manifest V3, "and the top content filtering extensions all have Manifest V3 versions available – with options for users of AdBlock, Adblock Plus, uBlock Origin and AdGuard."

For users of uBlock Origin , which runs on Manifest V2, "options" means using the less capable uBlock Origin Lite , which supports Manifest V3. ®
