Been using it since .6...i'm not sure I could work on a computer without Firefox anymore. The built in popup blocking and adblock extension makes my browsing nearly ad free..and tabbed windows are just too damned convenient to be given up.
I've tried Opera and MyIE but both of those are too bloated or have funky interfaces and neither one has an "adblock" extension that I ever saw. Also, neither of those is free, you have to pay to get rid of the built-in ads of their "free" Versions...Firefox is and always will be free
