Latest firefox install on FC2, fully patched

["skennedy@xxxxxxxx" <skennedy@xxxxxxxx>]

hi folks, I am having something of an issue installing the latest 
firefox ( or any firefox, for that matter ).  Everytime I try to install 
it, i get the error, "Could not find xpistub library" ( or something 
similar ).

I've installed the compat library, did a little googling, but have yet 
to come up with the solution.  Can anybody help me out?

Thanks

Sean
