G4 powerbook running OS 10.5.8 clicking on the download firefox 4 gives you the package file for firefox 5 instead, which has a big white slash through it because it doesn't work on this powerbook architecture apparently. any way to reinstall the version i just had on it before clicking upgrade?

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.x (Mac OS X 10.4 and later) can be found here:
