Chrome. It just feels a lot snappier than Firefox. The built in inspection / profiling tools are also pretty awesome. Oh, and source maps. I'm in love with them. Its awesome being able to debug running javascript + see console messages without having to leave the IDE (plus set breakpoints). I use GWT, so since even though chrome runs compiled java to javascript, I'm still able to debug it and see stacktraces in java, thanks to source maps.
