Quite possibly the most shittacular browser you may find on this fair interweb. Mozilla Firefox is a slightly better than a kick in the teeth. But only very slightly mind you. For all the woes that firefox may cause, one may try the highly effective, highly sexy Opera browser.
Jim: Oh noes! I can't download any porn and game demos with my shitty mozilla browser.

Russ: Might I suggest the Opera browser? Relatively speaking, it owns firefoxe's ass.

Jim: True dat

Russ: Fuck yeah!

Guys, let's get this right for once.

Mozilla is a company that creates a few internet-targeted applications, like their very good web browser called Firefox and an email client called Thunderbird, amongst other products.

Mozilla is also the name of an old web browser on which Firefox was then based. This browser itself was in turn based on the even older Netscape browser.
Guy: Man, Mozilla is an awesome browser.
Nerd: What, that old shit? At least get Firefox, dude.

Decent open-source web browser spawned from Netscape, but is now better than Netscape. It is standards compliant and could be considered the father of Firefox.

Mozilla is an open-source web browser.
open-source means that anyone who has some coding skills can get mozillas source code for free and modify the browser.

I used to use IE, but i switched to Firefox by Mozilla, now i get NO pop-ups, and everything is much faster than IE, If you have lots of pop-ups or IE is crashing all the time than switch to Mozilla its free.

6. Is that correct? It is? YES!
Me) Did you get the new Mozilla Firefox?
