a series of browsers, originating from Netscape, then made open source when the entire team was sacked by AOL, possibly one of the best browsers ever coded. All versions include an easter egg in the form of a message in About:mozilla which gives a fake bible quote similar to the Book of Revelations. the verse numbers at the end are important dates in the form of Month:Day 7:15, or july 15 was the day that AOL fired the entire netscape team and the Mozilla project was born.

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.

The bestest browser ever. Nearly everything on the web will render as well or better in Mozilla than Internet Explorer. People like to complain because Mozilla doesn't support all this junk that Microsoft made and integrated into their browser to hide the fact that it's a load of crap and crashes all the time

The best {web browser - mail client} existing on earth.
Opensource, regularly updated, and secure.

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.
