In step 2 (slide icon to applications) the firefox symbol comes up with a circle and line through it (like a do not enter). I slide the icon over and it won't open. Says "not supported by this architecture". I have a Mac. I had Firefox (but replaced it with newer version) and now I have no Firefox.

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:
