I use chrome for gmail, and Firefox for everything else. And it's quite quick on Linux. In fact, with that send.firefox.com bit that was talked about earlier, I just sent them a message and asked them to build that link directly into Firefox, so I can tell my friends who want to share files with me (I do a lot of charter sailing), 'hey, just open firefox and click Tools->Send'. No dropbox or anything else needed. I think it could be a killer feature.
