>Also, they are quick to implement most "features" Google implements, no matter how user-unfriendly it may be.

I fail to see how "implementing manifest v3" is user-unfriendly. I can see how people think that way, because "implementing manifest v3" is being conflated with "removing blocking webRequest API". However, there really isn't any indication that mozilla is doing the latter. For instance, you could implement manifest v3 but still supporting v2, or drop v2 but still keep the blocking webRequest API as a vendor specific API. There are good reasons to do the former, to allow firefox to work with extensions built for chrome, so I don't see any issues with mozilla implementing v3.
