I'm not sure I agree that Mozilla bears no responsibility for Web feature bloat. While you're right that Google currently appears to be stuffing every feature imaginable into their web browser at a breakneck pace in a desperate attempt to make it literally impossible for anyone else to write one, other browser vendors don't need to take it lying down. Imagine if Mozilla, Apple, and (pre-Chromium-fork) Microsoft all collectively agreed not to implement any more Web features: would websites really give up ~30% of their audience (including the lucrative iPhone crowd!) just to use some Chrome-only dingus? As a nonprofit, Mozilla is in a great position to lead a charge like that. But they've chosen instead to make the problem even worse. On top of everything Google does, Mozilla also creates and implements its own dubiously necessary features (WebVR comes to mind) and uses venues like the Mozilla Hacks blog to promote them to developers.
