Just trying Chrome now, and it seems wonderfully fast compared to FF...
For some things yes, for other things it's slower than FF (or even IE).
Browser choice is all about trade-offs. What works for one doesn't work for all.
FF is becoming a bit of a bloaty hog. I've got 6 tabs open, none of which are displaying anything big or complex and FF is taking up a monstrous 360MB of memory. Bonkers.
