About Manifest v3 firefox
To run on. We’re working on our own design that puts users in control, including early work by our Outreachy intern Richa Sharma on a project to give users the ability to decide if extensions will run in different container tabs (bug 1683056). Stay tuned for more information about that project!Code execution: Dynamic code execution in privileged extension contexts will be restricted by default (bug 1687763). A content security policy for content scripts will be introduced (bug 1581608). The existing userScripts and contentScripts APIs will be reworked to support service worker-based extensions (bug 1687761). Implementation timelineManifest v3 is a large platform project, and some parts of it will take longer than others to implement. As of this writing, we are hoping to complete enough work on this project to support developer testing in Q4 2021 and start accepting v3 submissions in early 2022. This schedule may be pushed back or delayed due to unforeseeable circumstances.We’d like to note that it’s still very early to be talking about migrating extensions to Manifest v3. We have not yet set a deprecation date for Manifest v2 but expect it to be supported for at least one year after Manifest v3 becomes stable in the release channel. #2 Mozilla expects to launch extensions Manifest V3 support in Firefox in late 2022 Mozilla plans to introduce support for the extensions Manifest V3 in the organization's Firefox web browser in late 2022. Preview versions are already available in development editions of the web browser.While Mozilla plans to introduce support for Manifest V3 in Firefox, it won't remove support for APIs that are essential to privacy extensions. Content blockers and other privacy extensions will continue to function in Firefox as before, provided that developers continue to support them. Firefox extensions won't be limited by Manifest V3Mozilla announced in 2019 that it would implement support for Manifest V3 in Firefox but would make adjustments to certain limitations. A new blog post on the Mozilla Add-ons Community blog sheds light on the adoption and the differences between Mozilla's and Google's implementation.The decision to remove the blocking part of the WebRequest API and to replace it with the limiting declarativeNetRequest API was at the center of the controversy. Mozilla notes that the new API limits "capabilities of certain types of privacy extensions without adequate replacement".Mozilla will keep the WebRequest API in Firefox to make sure that privacy extensions are not

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
