Firefox has added a lot of awesome developer tools lately and seems to be responding to the developer community in a great way. Has that made you switch to or continue using Firefox? Or is chrome your browser of choice? Maybe even safari or IE?
I don't have a 'main' browser. I use Firefox as my development browser, Chrome for office apps, and Safari for general reading. It's not paranoia, it just lets me keep things separate in a very easy way.
I really like Safari's Reader and that feature alone keeps me on Safari. Readability and other similar plugins on Chrome are nice, but I don't find them as well done as Reader.
