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

    Yes.

    I really appreciate the honesty, thank you. I now don’t have to care that those downvotes are rational.

    Following this same logic I imagine you downvote news of any treatments that extend the life of cancer patients because the new treatments aren’t full cures.

      Except in this case, the full cure also exists already and you’re trying to push the temporary treatment instead, for no good reason.

        There is no full cure. Nothing will offer a Chrome based browser support Manifest v2 after July. Your “cure” is “give up now”. Which, hey, if you want to, go for it. But for those that don’t for their own reasons, why are you so upset about them having the info about other browsers? I’m offering people information on a option that will preserve the functionality of manifest v2 Chrome based browsers or if they’re already using them that are still working meanwhile the article we’re talking about is referencing that functionality being removed early.

        I find it bizarre that these downvoters are so obsessed with people not having this information. How is this information in peoples hands hurting YOU so much? If you don’t want to use Vivaldi? Don’t! I’m not your dad. Move on and the people that want this info have it.

          The full cure is a non-Chrome-based browser, obviously. The notion of “some critical functionality someone needs in a Chrome based browser” would violate web standards and is therefore invalid bullshit and a cynical attempt to move goalposts.

          Why are you arguing in bad faith?

            I know, I use one as my primary browser actually!

            I’m not arguing in bad faith. I want to have a Chrome based browser with Manifest V2 in addition to that. For those that have the same desire, I’m offering info on that. Thats it.

            Wrong. There are browsere whose adblocker doesn’t depen on MV2 or MV3. Why are you arguing in bada faith?

              There are Chrome based addons that require manifest V2 that are NOT adblockers. Again, just because you want it for adblocking doesn’t mean your use case is the only one that exists.

                The use case of 90% of people doesn’t include extensions at all…
