I downloaded the newest version of Firefox to my lamp globe iMac and was unable to run it. The old version is now gone. Can't give all detail why that happened. Would like to either make version 4.0 work, or find an older version on the Mozilla site that will get me back to where I was.

Beginning with Firefox 4, Macs must have an Intel x86 processor (which you do NOT have; yours is a PPC Mac) and OSX 10.5 or higher

The good news is that Firefox 3.6.24 still supports OSX 10.4 and Macs with the PPC Mac architecture. The bad news is that support for the Firefox 3.6.x series is likely to end in the first quarter of 2012.

You can try the third-party product TenFourFox that supports PPC Macs. Firefox 8 version of TenFourFox is available. The product is based on Firefox released versions. All support is provided by the developer, not by this site:
