simplicity ? wait till you get infected with those annoying spywares ! and firefox is as simple as IE, its just more secure and is less targeted by advertisers and virus coders!
lol spywares don't exist on my pc I make sure they don't becuase of the programs i have + like i said i'm lookin forward to ie7
FireFox is a great FREE powerful browser.

Samer did you try FireTune?
i suggest you read the other firefox topics.
you won't regret the switch ;)
i tried it and didn't like it, regardless of what people say =P my opinion still rules lol
i made the switch abt 2 months ago, and i dont regret it ;) i least i dont get those annoying security warnings when im accessing some sites, or some annoying popups while surfin the net
I have nothing against IE, but it has the nasty habit of behaving erratically when I open more than say 15 windows (I always do that! - I know, I'm sick).
Plus the development on IE seems to be frozen. They only fix stuff, and add a stupid feature every year or so.
Not mentionning all the spyware that gets stuck to IE.

For the spyware, I advise you to check microsoft anti-spyware, it's great. (download it without registering your PC if you dont have an original windows install)
Well they are some disadvantages to firefox, though, mostly some menu effects do not look as pretty as in IE, and some rare pages lack functionnality. It is not the fault of firefox but that of the page developper who used non-standard IE features in his page.

you could download themes for firefox.
I'll always stick with IE becuase it is so simple and IE 7 is intended to be a recode of the browser including new security features, tabbed browsing and other details.
5 days later
I like/dislike IE , i think its still a gr8 browser although there are numerous alternatives , as long as IE is not hijacked I still continue to use it , and the only feature i miss in IE is the tabbed browsing which is coming in IE7 and a pop up blocker already exists with IE !!
