I'm using FF for quite a long time now. The new one (Firefox 3) is one of the best browsers I've used so far (And I used alot of 'em). Cool abilities, some nice add-ons and stuff :)
Mozilla Firefox is the best internet browser yet, besides Mac's Safari. I have Firefox, because Internet Explorer is just a pile of trojan horses. You can also open new tabs, unlike Explorer. Firefox Rules!!!
i forgot what its called i believe its like Refresh Stop one button. It combines the refresh and stop button so when you click the refresh button it changes to stop.
also duplicate tab and Undo Closed Tab
