Downloaded Firefox 4, replacing older edition, which worked well. Icon of new version came up with circle with slash on it, and when I attempted to open the new Firefox, the Mac said it was not supported by the architecture.

What's the problem and solution? Will it not work with G5 models?

For older Macs that aren't supported in Firefox 4.0, try TenFourFox for PowerPC's running Mac 10.4.11 & 10.5.8 .
