FWIW, I redrew the Firefox, Thunderbird and SeaMonkey icons for ArcaOS. (They're the same design, just updated from upstream, rescaled, and touched up.) If you have any ArcaOS DVD you can find them zipped in the \CID\SERVER\MOZILLA directory - feel free to take and use them, since obviously we have no IP claim on them. As you say, you would probably want to delete the 24-bit devices if compiling them into the binary.
