Run Firefox 2 and Firefox 3 beta together in OS X

If you’re a Mac user running OS X and want to be able to use Firefox 2 and a beta of Firefox 3 at the same time, you can either do some manual work or let MultiFireFox handle it for you automatically.

Make sure you have Firefox 2 installed, then grab the DMG here and it will install Firefox 3 without disturbing your Firefox 2 installation and the MultiFireFox app.

The first time you launch MultiFireFox it will ask you to setup a profile. From then on when you launch MultiFireFox you will be able to choose which Firefox version you’d like to open.
