I've been using Firefox forever but the problem is - it's now too big. Because it's - like you mention - following Chrome. To stay relevant, FF implements all the bloat Chrome churns out. Even worse, it's tempted to follow Chromes' extension manifest to stay compatible.

So I meant it looks like a lost battle. And it may be better to reboot to a smaller, nifter browser that a small team/community can handle.

edit: and of course cut all ties with Google financing.
