I have OSX 10.5.8 and I keep installing FireFox, but it keep disappearing. When I try to download the newest version, my software isn't compatible because I DON"T have the intel "chip. What can I do to reinstall an older version of Firefox?

Firefox not only disappears from my dock but also from my Applications folder. I tried to downl0ad it again today (5/19/2011), however, it says my system isn't compatible because I don't have an Intel processor. Any suggestions. I have problems with Safari and like to use Firefox but can't if it keeps disappearing and then Mozilla tells me that I can't install after I have already downloaded the application.
