Firefox Beta is a beta (second) release of the new version.
Firefox Aurora is an alpha (first) release of the new version.
A Firefox Nightly release is whatever was checked in up to last night.
As of September 2, 2011 there are four active versions of Firefox:
Firefox 6 - The most stable version of Firefox. It is safe for millions of users. and is qualified by the QA.
Firefox 7 (Beta) - An upcoming look at the newer Firefox is is pretty stable and safe. It is not recommended for everyone. It can be downloaded by anyone though and is mostly for Beta testers¤users. Tested by the QA but not recommended.
Aurora (Firefox 8) - An even less stable version of Firefox. It is not even called Firefox it is called Aurora. I am currently using Aurora version 2 right now. I do not see a difference (so far...I downloaded it only 30 minutes ago). It is not recommended for most people so if you are a regular person I would not recommend downloading this. Accepted by the QA but Highly NOT recommended.
Nightly (Firefox 9) - This is the least stable version of Firefox out there. I personally would not recommend this unless you are a programmer or know what you are doing. I haven't downloaded the Nightly version (yet), so I don't know what the difference is, but I do know that is is NOT ACCEPTED by the QA so you risk yourself by downloading it. If you have more questions just go to the Mozilla website and ask questions on that.
