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.

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

TL;DRGoogle Chrome is set to make sweeping changes to how extensions work via its transition to Manifest V3, but privacy advocates warn this could deal a major blow to popular tools like ad blockers.Over the next year, developers will scramble to update their extensions before Google begins disabling the existing Manifest V2 standard in mid-2024. Users meanwhile face uncertainty over whether their favourite plugins will retain full functionality or see their protections weakened.This controversial update from Google has been years in the making yet still faces criticism, and rightly so.A Primer on Browser Extensions - Manifest Standards: V2 vs V3Web browser extensions allow users to enhance their browsing experience through tools that can block ads or trackers, add functionality to websites, alter browser behavior and more. All major desktop browsers support extensions, though policies differ on capabilities between browsers like Chrome, Firefox, Safari and others.Regardless of the browser, all extensions require a basic configuration file called a manifest to function properly. This manifest.json describes the extension’s capabilities, permissions required, icons displayed and other identifying metadata. For example, here is uBlock Origins manifest fileThe current dominant version of this specification is Manifest V2, first introduced by Chrome in 2011. It has since become the de facto standard used by Chrome, Firefox and other browsers to ensure extensions work as expected and don’t access more user/system data than necessary for their function.Manifest versions act like programming language updates - they often tighten security, introduce new capabilities or reshape how existing features work. That’s precisely what Google aims to achieve with Manifest V3, though in a way that has serious implications for the ad blocking and privacy extension communities. Buried under claims of "security" and "privacy" are more questionable motives regarding Google's reliance on tracking users and serving ads.As YouTuber Nick puts it:"Google's main business model relies on serving ads and tracking users...their real interests are 'to use all this free stuff to track you, create a profile and push ads.'" This context is crucial to understanding their promotion of Manifest V3.At its core, Manifest V3 aims to replace WebRequest - the backbone API enabling ad blocking and content filtering extensions such as uBlock Origin - with a more limited alternative called DeclarativeNetRequest.Where WebRequest allows intercepting and reacting to network requests in real-time, DeclarativeNetRequest requires blacklists to be pre-defined without access to page contextual data. This directly threatens how popular privacy tools operate.AdGuard, a prominent ad blocking extension maker, helpfully summarized key differences:WebRequest provides raw access to HTTP headers and body, DeclarativeNetRequest does notWebRequest supports dynamic rules executed on every request, DeclarativeNetRequest requires static rules defined upfrontWebRequest responses can be modified, DeclarativeNetRequest cannot modify responsesDeclarativeNetRequest has strict quotas on rule sizeRestrictions on Cross-Origin

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.
