I use Firefox also... When I first got online years ago (AOL) I downloaded Netscape 2.0 and used it up until Mozilla, then Firefox came out. i use Opera for testing my sites and once in a great while I'll use IE to look at them...
Its looking like FireFox is defiantly the browser of choice here anyway.. I too only use IE for testing..
I use both. I prefer Firefox but I am on dial-up and my ISP has an accelerator that only works with IE. I use FF for stumbles, and most of the forums I use and I use IE for pages that take longer to load.
i only have IE now, but i've use firefox and i'd have to say it is better, but not a lot of difference really
FF as probably only because i'm used to it after using it for years.. Seems to be getting slower though in recent times, and have thought to switching to ie..
I've found that less "virus's" and other malicious code winds up on my laptop with firefox... IE seems to let everything through... Then again, I used IE6, don't know about the new version...
