There is no Manifest V3-based uBlock Origin, so the developer recommends uBlock Origin Lite, a 'pared-down' Manifest V3-compliant version of the extension. Like uBlock Origin, uBlock Origin

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

Limited in providing the functionality they are designed for. The organization will implement the declarativeNetRequest API for compatibility reasons according to the blog post.Mozilla will "continue to work with content blockers and other key consumers of this API to identify current and future alternatives where appropriate".Firefox will also support Event Pages in Manifest V3 and introduce support for Service Workers in future releases.Developers may turn on the preview in the following way in current development editions of the browser:Load about:config in the web browser's address bar.Confirm that you will be careful.Search for extensions.manifestV3.enabled and set the preference to TRUE with a click on the toggle.Search for xpinstall.signatures.required and set the preference to FALSE.Restart Firefox.Extensions may then be installed via about:debugging. Permanent installation of Manifest V3 extensions is possible in Nightly and Developer editions of the Firefox web browser. The implementation is not complete at the time of writing. #3 Mozilla reaffirmed this week that its plan has not changed. In "These weeks in Firefox: issue 124", the organization confirms that it will support the WebRequst API of Manifest v2 alongside Manifest v3. Again, a reminder that Mozilla plans to continue support for the Manifest v2 blocking WebRequest API (this API powers, for example, uBlock Origin) while simultaneously supporting Manifest v3. #4 Here's a good post about MV3 changes proposed for Firefox's UI: #5 Mozilla plans to add support for Manifest v3 browser extensions to its online store – addons.mozilla.org – so developers can have them cryptographically signed for distribution.Manifest v3 (Mv3) refers to a set of APIs and capabilities that are intended to become the new standard for browser extensions. It's a software architecture revision initially proposed by Google for Chromium-based browsers and subsequently endorsed by Mozilla for Firefox (Gecko-based) and by Apple for Safari (WebKit-based).Starting Monday, November 21, developers will be able to upload Mv3 extensions for signing. As a result, those using Firefox Nightly and Developer Edition will be able to test extensions refactored for the new rules, prior to the spec's general availability with the scheduled January 17, 2023 release of Firefox 109. #6 And so it begins... MV3 everywhere. #7 I am sorry to see Firefox caving in to Google and MV3 like this. I had really hoped FF and Mozilla would stick to their guns and not go along with MV3. Now I wonder about the specialty type browsers like Avast/AVG Secure browser or Brave. There is no Manifest V3-based uBlock Origin, so the developer recommends uBlock Origin Lite, a 'pared-down' Manifest V3-compliant version of the extension. Like uBlock Origin, uBlock Origin

Both uBlock Origin and its smaller sibling, uBlock Origin Lite, are experiencing problems thanks to browser vendors that really ought to know better.Developer Raymond Hill, or gorhill on GitHub, is one of the biggest unsung heroes of the modern web. He's the man behind two of the leading browser extensions to block unwanted advertising, the classic uBlock Origin and its smaller, simpler relation, uBlock Origin Lite. They both do the same job in significantly different ways, so depending on your preferred browser, you now must make a choice.Gorhill reports on GitHub that an automated code review by Mozilla flagged problems with uBlock Origin Lite. As a result, he has pulled the add-on from Mozilla's extensions site. The extension's former page now just says "Oops! We can't find that page". You can still install it direct from GitHub, though. The good news is that the full-fat version, uBlock Origin, is still there, so you can choose that. Hill has a detailed explanation of why and how uBlock Origin works best on Firefox. It's a snag, though, if like The Reg FOSS desk you habitually run both Firefox and Chrome and wanted to keep both on the same ad blocker. That's because, as The Register warned back in August, Google's new Manifest V3 extensions system means the removal of Manifest V2 – upon which uBlock Origin depends. For now, it still works – this vulture is running Chrome version 130 and uBO is still functioning. It's still available on Google's web extensions

En una controvertida decisión, Google ha limitado la disponibilidad de la popular extensión de bloqueo de anuncios uBlock Origin en su navegador Chrome: al visitar la página de dicho complemento en la Chrome Web Store, el navegador de Google muestra un mensaje indicando que la extensión "ya no está disponible porque no sigue las mejores prácticas para extensiones de Chrome". Como resultado, los usuarios de Chrome que tenían instalada la extensión ahora solo ven la opción de eliminarla, mientras que el botón para agregarla a Chrome ha desaparecido por completo. Además, en ciertas versiones como Chrome Canary, los usuarios han difundido que Google ya deshabilita automáticamente uBlock Origin y otras extensiones al iniciar el navegador, forzando su eliminación en algunos casos.Sin embargo, al acceder a la página de uBlock Origin desde otros navegadores basados en Chromium, como Edge, Arc, Vivaldi o Chrome, sigue siendo perfectamente posible, todavía, instalar la extensión en cuestión.

Updates: uBlock Origin Users Transition to Manifest v3

States: Individuals must have the ability to shape the internet and their own experiences on it. That philosophy drives our approach to Manifest V3.More creative possibilities for developers — We’ve introduced a broader range of APIs, including new AI functionality that allows extensions to run offline machine learning tasks directly in the browser.Support for both Manifest V2 and V3 — While some browsers are phasing out Manifest V2 entirely, Firefox is keeping it alongside Manifest V3. More tools for developers means more choice and innovation for users.Giving people choice and control on the internet has always been core to Mozilla. It’s all about making sure users have the freedom to shape their own experiences online.No limits on your extensions with Firefox​Google began phasing out Manifest V2 last year and plans to end support for extensions built on it by mid-2025. That change has real consequences: Chrome users are already losing access to uBlock Origin, one of the most popular ad blockers, because it relies on a Manifest V2 feature called blockingWebRequest.Google’s approach replaces blockingWebRequest with declarativeNetRequest, which limits how extensions can filter content. Since APIs define what extensions can and can’t do inside a browser, restricting certain APIs can limit what types of extensions are possible.Firefox, however, will continue supporting both blockingWebRequest and declarativeNetRequest — giving developers more flexibility and keeping powerful privacy tools available to users. We’ll keep you updated on what’s next for extensions in Firefox. In the meantime, check out addons.mozilla.org to explore thousands of ways to customize your Firefox..
