Just got around to installing a 32 bit Firefox on my x86_64 fc4 test system. The installer (and presumably the binary) is linked against libstdc++.so.5, which doesn't exist on my machine in either architecture. In FC3, this was installed in the compat-libstdc++ package, but I can't find that with yum. I'll leave the arguments about making YET ANOTHER incompatible change to the C++ interface for another day. But surely this package exists somewhere, no? Andy
