We just want to revert back to the previous version that WILL run on our PPC architecture. We don't want to buy a new computer just for Firefox. Where can we uninstall this one and download/install the older one???

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.
