I have MAC OS X 10.4.11 and downloaded the FireFox 7. It replaced my old version but I cannot run it on 10.4.11. Now I have NO FireFox and I prefer it to Safari. What can I do to get the old version back?

Chosen solution

Firefox 4 and later require at least OS X 10.5 and an Intel Mac.

You are unfortunately out of luck with an Intel Mac and OS X 10.4.11
Best would be to update to OS X 10.5 or later if you want to use Firefox 4 and later versions (current is 7.0.1).
There is a Firefox 7 compatible third-party version TenFourFox from www.floodgap.com for a PowerPC Mac, but no alternative for an Intel Mac with Mac OS X 10.4.

Firefox 3.6.x (Mac OS X 10.4 and later) can be found here:
