Firefox is secure and standards compliant. Internet Explorer has security holes and poor standards support.

An awesome web browser from Mozilla. It was originally derived from Mozilla's (Seamonkey) code, but now has plenty of coding of its own. It supports W3C's standards and is quite secure. Best of all, it doesn't have support for Microsoft's security hole (read: gate for hackers to enter your computer) known as ActiveX, nor does it have most of the problems Internet Explorer has.
Mozilla will pay anyone $500 bucks for volunteering to fix security holes in its software, which is free (yes, as in speech, but also as in beer). That's pretty generous.

The most kickass web browser out there now (developed by Mozilla). It is so superior in comparison to Microsoft's Internet Explorer. Try it! You'll wonder how you ever surfed the net without it.

You won't be disappointed.

Going on the internet without firefox is like walking into an Al-Qaeda camp with nothing but american flag designed underpants.

Firefox is to Internet Explorer as flash drives are to floppy disks.
Stop using that sorry excuse for a "Web browser" and download firefox. It's free and it's open source.

An excellent, under-rated browser. People think only anti-Microsoft script kiddies use it, but in reality, everyone should love it because of Firebug, the most amazing and useful extension ever created.
Firefox Hater: Only n00bs use Firefox! Internet Explorer is just as good!

Firefox/Firebug User: Wrong. Download Firefox and Firebug and you'll see why Firefox essentially pwns Internet Explorer.
