More to the point, the stakes are really high for FF now.
I use and love FF, but FF's market share is very low and shrinking. If they can't do anything to turn that trend around, web developers will ignore it, and it will become useless for many sites.
FF users have to wish/hope that FF rights this ship, and that means they can't afford to lose any more users (and really, that they must somehow reverse course and acquire new users). So every update feels really important - the shrinking user base is an existential threat to the browser.
I think that is the wrong end of the stick. People complain about Firefox not because they hate it. They complain because they care. It is the same thing with Apple or in fact any other brands. They want it to be better, they want to come back or keep using Firefox. And they want more people to use it ( for one reason or another ).
So the saying good there is no such thing as bad publicity. Firefox still getting the upvote to front page or being complained is a good sign many user or potential user still give a damn.
I still love Firefox, I just dislike Mozilla's management.
