b: yea, why?
a: dude, just stop using it! download mozilla or firebird from mozilla.org and you will see what internet surfing really means!
b: ok, whatever.
Has the most useful plugins ever created, such as "FlashBlock" which completely eradicates flash ads on web pages that may slow down your browsing, and those annoying "Shoot the Ninja and get a free iPod!" ads. As well as Fasterfox, which optimizes the speed, and many more.
The great thing about this browser is that it DOESNT install crap on your computer without asking you prior to that...Internet Explorer by Microsoft, for example, randomly changes it's homepage, installs adware and spyware and third party crap without your knowing.
With a built in google toolbar (which, incidentally, doesnt take up 3/5ths of the screen like on IE), it makes searching a breeze.
Definitely the way to go for an optimized browsing experience.
-fsho get firefox
Firefox supports virtually all the plugins IE does, such as Flash, Java, RealPlayer, etc. You just click on where it says "download this plugin now" and it'll be installed automatically.
