Firefox > all other browsers.
My favorite browser is " Google Chrome " now.
I've been using FireFox since forever, but like 1-2 weeks ago I switched to Chrome since they released their extensions (which was the main element missing compared to FireFox, imo)... so well I tried out Chrome for about a week and then moved right back to FireFox something didn't feel right, so I guess my answer is that nothing beats FireFox.
Chrome > Firefox > Opera
Opera eats them all. If you know what is "mouse gesture" you know what I mean
