We have an older Mac Mini running OS X 10.5.8, PPC G4 1.2, and we tried to install the latest Firefox version. It installed and now will not launch on this "architecture"! NOW what do we do??? We want our old Firefox BACK!!!
We just want to revert back to the previous version that WILL run on our PPC architecture. We don't want to buy a new computer just for Firefox. Where can we uninstall this one and download/install the older one???

Firefox 4 versions and later do not run on a PowerPC Mac. Firefox 4 and later require at least OS X 10.5 and an Intel Mac.

Firefox 3.6.24 (Mac OS X 10.4 and later) can be found here:
