I downloaded Firefox 4 to my G5 Mac, 1.8 GHz PowerPC, Mac Version 10.5.8, cannot use it. Want to know how do I deinstall it. I have the Firefox 2CD, can I use this to deinstall. Thank you, Georgia Simms

Unfortunately, Firefox 4 supports only Mac OS X 10.5 and above on Intel hardware. The system that you are currently using is no longer supported by Firefox (details can be found here).

You can revert back to previous version of Firefox by following these steps:

  1. Open the Applications folder.
  2. Drag the Firefox application to the Trash.
  3. Download and install Firefox 3.6 from here.
