An internet browser that is rising in usage and popularity and claims better security and standards compliance than the defacto standard, IE. It does tend to take up a lot of memory and like any software has some issues.
Wow Yen, I just tried the new Firefox browser and I don't get any more virii or spams from all my favorite porn sites.

A decent browser made by Mozilla in 1998.
It rocks Internet Explorer's butt.
1. What browser are you using?
2. Firefox.

An awesome browser that has features that IE neglected. Popup blocking, tabbed browsing, keyword searching... extentions let you do mouse gestures and a lot more.

Oh, did I mention, it's faster too. And it's only 14 MB.
People come to me with their computer problems, saying that IE stopped working. I send them the Firefox as a solution, and later, they always thank me for it.

Simply the best browser out there. It will make you wonder why you ever used IE.
Why are you still using that outdated piece of crap IE when you can use Firefox?

Many people like to uninstall Internet Explorer if they plan on using Firefox for the rest of their lives, but this isn't possible because IE is integrated into Windows.
However, it is possible to *disable* access to IE using one of the following methods:
1. Select "Set Program Access and Defaults" from the Start menu. Uncheck each browser that you would like to disable access to.
2. From the Add/Remove Programs applet in the Control Panel, select "Add/Remove Windows Components." Uncheck the checkbox next to IE.
I disabled access to Internet Explorer after I installed Firefox.

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.
