[quote name='SevereTireDamage']What's the main difference between Mozilla and Firebird?[/quote]
Firefox is kind of the experimental, concept version of Mozilla. With that in mind, you'd think it would be buggy and crash a lot, but it doesn't crash that often; it's pretty stable overall. I'm using it and I really love how you can customize it with keywords. For example, I have it set to allow a quicksearch on Froogle; I just type in "froogle [name of game]" in the address bar and it returns the results of a Froogle search on that game. Same goes for Google, eBay, Amazon, or any other site you wish to search. You can set it up to use a keyword for that site. I also have set so that when I visit CAG, I don't have to type the full address; I just type "cag" and press enter, and it fills in the rest for me. It features the tabbed browsing of Mozilla, which is great, especially for loading links in the background while you continue to read the page you're reading. And like Mozilla, it has a bunch of add-ins you can download, as well as a built-in download manager. I still keep IE around for the 5% of sites that don't work with Firefox, but otherwise, I never go back to it.
