I used to use firefox. But i only use chrome now. Considering changing back to firefox. Google is just too big these days, got their fingers all up in my shit. Im not impressed.
Firefox has a great mail manager called webmailnotifier that I can't live without, so until Chrome gets that, it's firefox. Also, Firefox has been more stable in recent builds, so I don't see a need to change anytime soon. Also, some stuff in Chrome displays funny for me on some sites I visit.
