Chrome / Chromium Manifest V3 and Brave

And Vivaldi that have their "own" built-in ad blockers. I wonder how those will be affected by MV3. Do the browser devs make their own proprietary ad blockers or are they just borrowed from the Google store and will still carry the same MV3 burdens?C.H. #8 The built-in adblockers as for example Brave are not affected.They don't use an extension: Google's upcoming Manifest V3 update for extensions has the potential to break many ad blockers. But Manifest V3 will not prevent Brave from blocking ads. We built ad blocking into the browser itself so it will not be affected by Google changing its rules for extensions. Vivaldi: Manifest V3, webRequest, and ad blockers Vivaldi comes with its own built-in Ad and Tracker Blocker, tons of customization options, a built-in Mail and Calendar, and more. Will it follow Google’s strict reliance on Manifest V3? vivaldi.com #9 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. Mozilla not adopting MV3 sounds like a good idea in theory, but the effect of not doing so will mean extension developers won't be able to easily port their Chrome extensions to Firefox, thus they'll likely stop developing for Firefox altogether. Now I wonder about the specialty type browsers like Avast/AVG Secure browser or Brave and Vivaldi that have their "own" built-in ad blockers. I wonder how those will be affected by MV3. Do the browser devs make their own proprietary ad blockers or are they just borrowed from the Google store and will still carry the same MV3 burdens? Brave's ad blocker won't be impacted. Vivaldi believes theirs won't be impacted either. Can't speak for Avast/AVG; as far as I'm aware they haven't addressed whether it'll impact their browsers or not.@Gandalf_The_Grey Beat me to it. #10 Adblocking will continue to work in Firefox for now. So that's not a concern for the near future. Excluding this uncomfortable issue of ad blocking, I do think that MV3 is good for improving browser security. So Mozilla won't stay behind the pack and make it more difficult for extension developers. But I have doubts about how long they'll be able to keep supporting the old API. I think they should follow Brave and build their own browser integrated adblocker free from the MV3 impact. This

Manifest V3 Support on Brave? - Quality Assurance - Brave

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

Brave on LinkedIn: How Manifest V3 Will Affect Brave

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.

What Manifest V3 means for Brave Shields

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

Como se implementó en Manifest V2, el campo "web_accessible_resources" hizo que los sitios web y los atacantes pudieran detectar extensiones si decidían exponer recursos. Esto generó oportunidades para la creación de huellas digitales o el acceso a recursos no intencional. Manifest V3 limita la exposición, ya que restringe qué sitios web y extensiones pueden acceder a los recursos de tu extensión. En lugar de proporcionar una lista de archivos como antes, ahora proporcionas un array de objetos, cada uno de los cuales asigna un conjunto de recursos a un conjunto de URLs o IDs de extensión.En el siguiente ejemplo, se comparan los recursos accesibles a la Web entre Manifest V2 y Manifest V3. En el manifiesto V2, todos los sitios web podían acceder a los recursos especificados de forma predeterminada.

Will help them attract some users. Mozilla's implementation of Mv3 will differ in two critical ways from Google's. First, it will provide developers with access to the APIs Google considers too troublesome to retain."While other browser vendors introduced declarativeNetRequest (DNR) in favor of blocking Web Request in Mv3, Firefox Mv3 continues to support blocking Web Request and will support a compatible version of DNR in the future," said Shane Caraveo, engineering manager for WebExtensions at Mozilla, in a blog post. "We believe blocking Web Request is more flexible than DNR, thus allowing for more creative use cases in content blockers and other privacy and security extensions." #11 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. You may missed the fact that Mozilla will continue to support even MV2 addons for Firefox, the question remains for how long, but nobody knows that yet it's just speculation only #12 Mozilla highlights that its implementation of Manifest V3 differs from Chromium's implementation in two major ways:Firefox continues to support Manifest V2's web request blocking API next to Manifest V3's declarativeNetRequest API. Extension developers may use either in their extensions.Firefox will support Manifest V3's Event Pages, but will also continue to support Service Workers.Firefox's Manifest V3 compatibility will improve over the next year, according to Mozilla.Mozilla rolled out a new Unified Extensions button in Firefox Nightly already that relies on Manifest V3 and gives users greater control over the website access of extensions. You see how it looks in the screenshot ... #13 Firefox found a way to keep ad-blockers working with Manifest V3​ In a Tuesday blog post explaining the new extensions system, Mozilla says it adopted Manifest Version 3 to make things a lot easier for people developing extensions for both Chrome and Firefox. But while its implementation is largely meant to be cross-compatible, the organization says its version is different from Google’s in “some critical areas,” mainly security and privacy.Google also cited those areas when it added Manifest V3 to Chrome in 2021, calling the move “part of a shift in the philosophy behind user security and privacy.” But one of the changes in the update broke features in several popular content and ad-blocking extensions by removing a feature they used to block certain network requests (be.
