Chrome convert here to. Used to use FF but it started to really feel slow and bloated, trying chrome was very refreshing plus the few extensions I actually use are supported in both now
(adblock, flashblock, an exif viewer anf SABconnect).
I have come across a few sites that don't like Chrome much (mostly work-related things that dont work in anything bar IE), also I find the developer tools in Chrome half decent now so I find I use FF and firebug less and less for web dev stuff
