I started using Mozilla recently because cnet recommended it and because I suddenly came down with over a thousand viruses thanks to the hole in IE before SP2. (I use XP). Mozilla is very fast, much faster than IE, and has the wonderful perk of being able to open additional windows within the same browser without losing any of the other ones. I LOVE that feature. No more having to open additional browswer windows to go to other sites. Highly recommended! Much more secure than IE.
