Dave Martorana’s MultiFireFox, lets you run Firefox 2 and Firefox 3 beta side-by-side on Mac OS X without wiping or messing up your stable Firefox 2 installation profile. You can hit the command line, create a new profile and then customize the shortcut to each version of Firefox so that it launches the correct profile (or manually choose what profile you want at the start of each Firefox session), but that can be a pain — especially if you want to try out different plugin configurations in Firefox 3.
You can download the dmg, or the zip of the source if you want to dig around to port this to Windows and not only will you get Firefox 3 beta 3, but a very tidy little launching application. Upon running MultiFireFox for the first time, you will be instructed to create a second profile if you do not already have one (and the profile manager will start up automatically, no going into the command line to get it started). From that point, you can choose what profile and what version of Firefox you want to launch. You can even run the two side-by-side to test performance.

Hi folks!
There is a very different use for MultiFirefox:
I use MultiFirefox in connection with Vidalia for anonymous surfing and downloading! In connection with LaLL (Launch aLL) you are able to start Vidalia and MultiFirefox together. After launching, you only have to choose from your anonymous or default profiles, depending on whether you want fast or safe surfing. MultiFirefox also allows you (in conjunction with Vidalia) multiple (parallel) downloads as a “free-user” in RapidShare and cohorts. Usually they log your IP and also use cookies and your browsers history to suppress exactly those multiple downloads. MultiFireFox 2.0 lets you run up to 5 versions of FireFox side by side so you can manage up to 10 (!) Parallel downloads at the same time. MultiFirefox is a great solution, especially if you want to download many “.part-files”. Just use MultiFirefox and Vidalia and you’ll never need a paid account…
