Microsoft begins turning off uBlock Origin and other extensions in Edge
www.neowin.net
Microsoft is now in the process of turning off Manifest V2-based extensions in Edge, such as uBlock Origin. However, not everything is lost at this point.

The latest Edge Canary version started disabling Manifest V2-based extensions with the following message: “This extension is no longer supported. Microsoft Edge recommends that you remove it.” Although the browser turns off old extensions without asking, you can still make them work by clicking “Manage extension” and toggling it back (you will have to acknowledge another prompt).

At this point, it is not entirely clear what is going on. Google started phasing out Manifest V2 extensions in June 2024, and it has a clear roadmap for the process. Microsoft’s documentation, however, still says “TBD,” so the exact dates are not known yet. This leads to some speculating about the situation being one of “unexpected changes” coming from Chromium. Either way, sooner or later, Microsoft will ditch MV2-based extensions, so get ready as we wait for Microsoft to shine some light on its plans.

Another thing worth noting is that the change does not appear to be affecting Edge’s stable release or Beta/Dev Channels. For now, only Canary versions disable uBlock Origin and other MV2 extensions, leaving users a way to toggle them back on. Also, the uBlock Origin is still available in the Edge Add-ons store

    Brave will support it until it becomes inconvenient or difficult to do so as the Chromium base keeps moving. The more time goes on, the more work it’ll be for Brave to maintain this forked functionality.

    My guess is at some point Brave will discontinue V2 and say “just use the Brave inbuilt adblocker”.

    Regardless, Brave have their own skeletons in the closet… crypto, the Windows installer installing other Brave applications during browser install without consent (that one is straight up malware behaviour. Reminds me of the days of software installing Internet Explorer toolbars without consent), injecting their affiliate links when nobody asked, a CEO who donated money to homophobic causes more than once.

    E: my above theory was correct, sort of:

    We will keep Manifest v2 for as long as it’s still available in Chromium. We expect to drop support in June 2025, but we may maintain it longer or be forced to drop support for it sooner, depending on the precise nature of the changes to the code.

    They are only committing to enabling the disabled Mv2 code in Chromium. Once it’s removed altogether, Brave probably won’t bother keeping it and maintaining it. Basically, if you want Mv2, only Firefox and its derivatives are committed to keeping it.
