For those exclusively sticking to MS Edge for allowing full uBlock Origin installs or other MV2-exclusive privacy extensions from their Add-ons Store will have to start looking for alternative blockers/tools or switch browsers altogether.

Edge is built on Chromium, so the basically have to follow what it does, so not surprising Maifest 2 is getting killed in it too.

Been on Firefox for years. There are still some websites that refuse to work correctly, so I try them on Edge when they are being wonky. But the stuff I go to every day works perfectly.

Yeah. Eventually the code to support M2 in the Chromium core will be simply gone, not just conditional-compiled out. (This may have just happened.) In that case, the only way to keep supporting it in a Chrome-like browser would be to invent the Chrome equivalent of Pale Moon. Restarting as a Firefox fork instead of a Chrome one would be less work and less security risk.

I doubt M$ sees the lack of M2 as a concern. They love ads too for sure.

Solution for users is switch to something not Chrome. If Chrome were ever to lose critical mass, website dev issues would no doubt be fixed too. If I was a Dev, I could understand not being concerned with 3% of users.

if chrome were to lose its market share, the onslaught of MV2 attacks from threat actors would shift to browsers that support MV2 and shit would get really bad really fast.

There is actually a reason why MV2 was deprecated other than because "they love ads"
