Ok, I think I have figured out what the problem is: Firefox's JavaScript OSFile implementation loads libc.so.6 if it is available! That is, if you have the compat6x package installed, it loads /usr/local/lib/libc.so.6, even while /lib/libc.so.7 is already loaded. This wreaks havoc when it later tries to call libc functions via libffi, and the result is that it calls into a completely bogus PLT entry. Most of the time, this leads to a crash. So the easiest way to avoid the crash for now is to uninstall the compat6x package, and making sure there is no libc.so.6 in /usr/local/lib/compat. Then Firefox should start with no problems. As a better fix, please try dropping the attached file into the /usr/ports/www/firefox/files directory, then rebuild the firefox port from scratch, and reinstall it. -Dimitry
