Push Poll Silliness
I have neither bug nor bloat complaints with Firefox so I can't really even answer your poll question.
And you "screaming fan" nonsense is hysterical. Really? ANY program running on your rig makes your fan scream? BwaHAHAHAHAA!!! I get flawless performance out of Firefox on a 2 ghz laptop running XP, a 2ghz dual core running Win7, and THANK GOD for Firefox on my 1.8ghz running Windows 2000 with 512 mg RAM. I can watch Netflix on Win2000 with Firefox, a feat I haven't been able to accomplish elsewhere.
Firefox is the David to all the other Goliaths, making the fact that it works so well even more amazing. Kudos, Moz. Google has a big enough footprint in my world already.
