Two questions I haven't seen addressed by any coverage of this change: 1. Will the ultimate removal of Manifest V2 support affect other Chromium-based browsers, or only Chrome itself? If the support for Manifest V2 isn't removed upstream in Chromium, but only disabled in Chrome, then I would expect that we will end up in a world where other browsers (e.g. Edge, Brave, Opera) continue to allow the installation of Mani…
I work on adblocking at Brave. 1. Brave, Vivaldi, and Opera have all announced they'd maintain support for Mv2 past Google's deprecation date [1]. 2. Your guess is correct - one of Google's stated motivations is to make the extension review process easier and less error-prone; having a way to opt-out would be counterproductive in that regard. I strongly doubt they'd accept the PR upstream; there is a chance other pla…
The design has already been completed, in that mozilla has already done this in their implementation of manifest v3. The difficulty of convincing extension developers to support it should thus be no more difficult than convincing them to ship a firefox version of their extension.
