Outdated computer won't support new Firefox.

I have a Mac OS X Version 10.4.11. I just downloaded the latest Firefox and when asked 'Do you want to delete the existing file' (ie an older version of Firefox), I clicked yes. But when I tried to open the new Firefox, I got a message saying my computer won't support it. Is there a way I can either get my computer to open the new version, or else to again download the older version?

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

You can find the latest Firefox 3.6.x release in all languages and for all Operating Systems here:
