Incredibly good browser overflowing with useful features from the good folks at Mozilla. Tabbed browsing, a near-impenetrable popup blocker and general awesomeness compounded by the fact that you can add just about any feature you want using Firefox's plugin support make for a browser that simply trounces anything else. The only flaw is the name. They ought to call it Firebox because that'd be seriously awesome.
I can't believe how utterly awesome Firefox is. And yet, if only it were named Firebox, it might be ten times awesomer.
