Ublock manifest v3

Mozilla has reaffirmed its commitment to supporting both Manifest V2 and Manifest V3 for browser extensions, ensuring continued access to powerful privacy-preserving tools like ad blockers.This announcement comes as Google continues its phased deprecation of Manifest V2 in Chrome, which has already resulted in automatically disabling extensions that rely on the older framework, most notably, uBlock Origin, which counts 38 million users.Although Google developed Manifest V3 (MV3), other browsers like Firefox and Safari have also adopted it with their own implementations. The primary reason for this adoption is to maintain compatibility with Chrome extensions, which dominate the market. However, Mozilla has made key modifications to MV3, including keeping the blockingWebRequest API, ensuring that developers and users retain access to advanced privacy and content-filtering tools.Mozilla's statement, published earlier today, highlights its distinct approach to MV3. Unlike Chrome, which replaces blockingWebRequest with the more restrictive declarativeNetRequest API, Firefox will support both. This decision ensures that extension developers retain flexibility while allowing users to maintain their preferred browsing experience, including full-featured ad-blocking capabilities. The company emphasized that user choice and control over internet experiences are core to Mozilla's mission, citing Principle 5 of the Mozilla Manifesto — the belief that individuals should have the ability to shape their online experiences.Google abandons Manifest V2Meanwhile, Google has begun the widespread deactivation of Manifest V2-based extensions, including uBlock Origin, in Chrome. Reports from last week confirmed that some users are seeing their extensions disabled with a message stating they are no longer supported. While the rollout is gradual, Chrome users globally are encountering automatic removals, with limited options beyond switching to a Manifest V3-compatible alternative like uBlock Origin Lite. However, many privacy-conscious users argue that the Lite version lacks the robust filtering options of its predecessor.Mozilla's decision to support both Manifest V2 and V3 ensures that developers can continue to build powerful tools without restrictive API limitations. In contrast, Chrome users looking for similar functionality may need to explore third-party solutions or alternative browsers before Google completes the full phase-out of Manifest V2 by mid-2025.As Google accelerates its transition to Manifest V3, Mozilla's decision to maintain Manifest V2 support positions Firefox as one of the last remaining browsers where users can fully control their online experience. The Tor Browser is based on Firefox, so the same applies to that project. Both are on our list of the 12 most secure browsers that protect users' privacy, so

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.
