Chrome extension manifest v3

Google's latest Chrome update has disabled several widely used ad-blocking extensions, including uBlock Origin. This comes with the search giant moving to a new extension framework, Manifest V3. The update is being rolled out to improve security and privacy, but it has also removed key functionalities that ad blockers rely on.On Reddit and X (formerly Twitter), people reported Chrome disabling older extensions. A notification appears under the extensions tab in the browser's taskbar, informing users that the add-on has been turned off and is no longer supported.Manifest V3: Google's new extension frameworkManifest V3 is Google's updated standard for Chrome extensions. It aims to improve security, privacy and performance. The company states that the changes aim to reduce the risks of malicious extensions and limit potential data abuse. But the update also restricts the ability of extensions to modify web requests, a feature essential for ad blockers.Key extensions disabledAs Google phases out Manifest V2, Chrome users are seeing popular extensions, including uBlock Origin, become obsolete. Any extension that hasn't or cannot transition to Manifest V3 is being disabled, leaving users with limited alternatives, stated a report in the Verge.Impact on other browsersThe shift to Manifest V3 isn't limited to Chrome. Other Chromium-based browsers, such as Microsoft Edge, are also losing support for older extensions. Brave, a privacy-focused browser, has stated it can only provide limited support for Manifest V2 extensions once Google fully removes them from the Chrome Web Store, reported The Verge.Firefox and other browsers stand apartMozilla Firefox has said

As noted by uBlock Origin’s Raymond Hill on X (formerly Twitter), Google Chrome has begun disabling and suggesting the removal of extensions that are not updated for Manifest V3, as of Oct. 14. Google Chrome's long, long project to implement a new browser extension platform is seemingly going to happen, for real, after six years of cautious movement.One of the first ways people are seeing this is if they use uBlock Origin, a popular ad-blocking extension, as noted by Bleeping Computer. Recently, Chrome users have seen warnings pop up that "This extension may soon no longer be supported," with links asking the user to "Remove or replace it with similar extensions" from Chrome's Web Store. You might see a similar warning on some extensions if you head to Chrome's Extensions page (chrome://extensions).What's happening is Chrome preparing to make Manifest V3 required for extensions that want to run on its platform. First announced in 2018, the last word on Manifest V3 was that V2 extensions would start being nudged out in early June on the Beta, Dev, and Canary update channels. Users will be able to manually re-enable V2 extensions "for a short time," Google has said, "but over time, this toggle will go away as well." The shift for enterprise Chrome deployments is expected to be put off until June 2025.Google has said that its new extension platform was built for "improving the security, privacy, performance, and trustworthiness of the extension ecosystem." The Electronic Frontier Foundation (EFF) disagrees most strongly with the security aspect, and Firefox-maker Mozilla, while intending to support V3 extensions for cross-browser compatibility, has no plans to cut off support for V2 extensions, signaling that it doesn't see the big improvement.

#1 Two years ago, Google proposed Manifest v3, a number of foundational changes to the Chrome extension framework. Many of these changes introduce new incompatibilities between Firefox and Chrome. As we previously wrote, we want to maintain a high degree of compatibility to support cross-browser development. We will introduce Manifest v3 support for Firefox extensions. However, we will diverge from Chrome’s implementation where we think it matters and our values point to a different solution.For the last few months, we have consulted with extension developers and Firefox’s engineering leadership about our approach to Manifest v3. The following is an overview of our plan to move forward, which is based on those conversations. High level changes​In our initial response to the Manifest v3 proposal, we committed to implementing cross-origin protections. Some of this work is underway as part of Site Isolation, a larger reworking of Firefox’s architecture to isolate sites from each other. You can test how your extension performs in site isolation on the Nightly pre-release channel by going to about: preferences#experimental and enabling Fission (Site Isolation). This feature will be gradually enabled by default on Firefox Beta in the upcoming months and will start rolling out a small percentage of release users in Q3 2021.Cross-origin requests in content scripts already encounter restrictions by advances of the web platform (e.g. SameSite cookies, CORP) and privacy features of Firefox (e.g. state partitioning). To support extensions, we are allowing extension scripts with sufficient host permissions to be exempted from these policies. Content scripts won’t benefit from these improvements, and will eventually have the same kind of permissions as regular web pages (bug 1578405). We will continue to develop APIs to enable extensions to perform cross-origin requests that respect the user’s privacy choices (e.g. bug 1670278, bug 1698863).Background pages will be replaced by background service workers (bug 1578286). This is a substantial change and will continue to be developed over the next few months. We will make a new announcement once we have something that can be tested in Nightly.Promise-based APIs: Our APIs have been Promise-based since their inception using the browser.* namespace and we published a polyfill to offer consistent behavior across browsers that only support the chrome.* namespace. For Manifest v3, we will enable Promise-based APIs in the chrome.* namespace as well.Host permission controls (bug 1711787): Chrome has shipped a feature that gives users control over which sites extensions are allowed
