From where I stand, it looks like they're trading one of their big advantages for a massively reduced maintenance burden which will unquestionably allow them to compete better on every other front. It may or may not pan out, but I think we can all agree that some change of trajectory from the past few years is needed if Firefox hopes to stay relevant. You're free to think that Mozilla leadership is incompetent, but in this particular instance I think their stance is grounded in sound reasoning, as inconvenient as it is undoubtedly is for some power users.

Source on me saying that? I think they are making a few dumb decisions, but that's putting a lot of words in my mouth.
FF has very few advantages. They aren't competing on speed, mind-share, ease-of-use and now they aren't competing on reliability of add-ons. I get that this can help them focus, but pushing away their limited user-base is like using an axe to help a sinking ship.
