Undo Firefox Update

I recently updated Firefox to 4.0 and much to my dismay, I couldn't use the browser after the update. I received a little pop-up warning telling me that I can't use this application with my current OS. I'm on a Mac running Tiger. The new update doesn't work a machine that's this old.

To revert Firefox to it's original state, I just needed to find a previous version of Firefox and install it. Firefox's website provides a nice little walk-through to find previous versions of Firefox. ANY version of Firefox, and in any language, for any platform.

Once you read the instructions, visit their FTP site to download the version that you want.
