The best web browser ever created. It has many advantages over Google Chrome and Internet Explorer. For example: It doesn't spy and track you, doesn't randomly change its homepage and Install adware, and doesn't take bloody ages to load a webpage.
Person 1: There! Firefox just got finished loading that newgrounds game.
Person 2: Really? My IE just started loading the Newgrounds logo.

One of the safest, most efficient and bullshitless browsers out there (among others such as Opera).

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.

Mozilla's answer to Internet Explorer. Firefox includes popup blocking, tabbed browsing, extensions, a download manager, and is much more secure than Internet Explorer, because it doesn't use ActiveX or active scripting.

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.
When I was a newb, I used Internet Explorer, but now that I know more about how the Internet and computers work, I've switched to Firefox for good.
