Mozilla is the maker of the famous Firefox browser which has been using its own web engine called “Gecko” since forever, and hence, is not affected at all by these moves from Google.
You answered your own question. It doesn’t effect FF.
But, I do agree they should use the downgrade in functionality of V3 as a point for advertising FF.
What good would advertising “Still supporting Manifest V2” do for your average user? They also wouldn’t want to openly advertise that “Your ad block still works with us”.
that’s also probably a factor in why they don’t say anything, big moneypants might say something
Didn’t they remove XUL extensions to make their extension interface compatible with inferior chrome web extensions?
I just did a quick online search and it seems like the reason for removing that was that it was way too much work to maintain and stopped them from implementing performance improvements for Firefox. Apparently it was also a lot of work for extension developers, since they had to update their extensions constantly.
That’s just what I read tho, I wasn’t there when XUL extensions where still a thing.
