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.
