I mainly use FireFox. I use Chrome for its Incognito mode from time to time, and I use Safari to control my iPhone's bookmarks. I have IE 8 (using Windows 7 beta right now) and even though it's all "new" it's still crap garbage. Windows 7 is nice tho. haha.
yeah the "Incognito" feat on chrome is cool...after i reformated my pc i just decided to install FF instead of hwo i had it, FF,chrome,opera & safari...i used to use a diff browser for multiple email accounts on the same domain...
