I downloaded the newest version and there is a Circle with a slash through it over the firefox icon. When I click on it the message is the system does not support this version. How do I reinstall the previous version?

I updated firefox. When I did there was a circle with a slash (as in No!) across the firefox icon. I clicked on it to open the browser and the error message reads: the application firefox cannot be launched - 10661

How do I go to the previous version that worked just fine?

Firefox 3.6.x is the last available from Mozilla for PPC Macs.

For older Macs that aren't supported in Firefox 4+ versions, try TenFourFox for PowerPC's running Mac 10.4.11 & 10.5.8 .
