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
Of course, but extra work is required for third party browsers vs just using windows built in browser designed to be managed using entraID / intune.
Companies don’t like to pay extra.
It’s no different than controlling add-ons via GPO like we did in the old days of on-prem. No extra cost associated.
Tell that to oir IT partner that we outsourced our IT to…
Your outsourced IT provider charges for simple configuration changes? That’s a yikes from me. I worked in MSPs for years and those sort of changes were always covered in the standard contract.
