> What exactly is your gripe with MV3?
Running an adblocker is the defining feature of the extensions API. ublock origin has 5x as many users as the second-most-popular extension [1]
Supporting ublock isn't just a nice-to-have add-on feature for an extension API, it's literally the only thing most users care about.

But MV3 supports uBlock Origin Lite.
Which, in my experience, blocks ads just as well, but also lets pages load significantly faster.
MV3 supports uBlock.
Reading comprehension is the defining feature of a good commenter.
Firefox's MV3 implementation doesn't remove the original netRequest API though IIRC.
