All of the user .mozilla/plugins directories are empty.

Wow, sweet.

Okay, the broken user is using plugins from /usr/lib/firefox while the 
others use /usr/lib/mozilla.  I didn't even know there was a 
/usr/lib/firefox.

The broken user has a "null plugin"

So, I did this:

im# find . -name '*libnull*' -print
./firefox/plugins/libnullplugin.so
./esc-1.0.1/xulrunner/plugins/libnullplugin.so
./firefox-2.0.0.16/plugins/libnullplugin.so
./seamonkey-1.1.11/plugins/libnullplugin.so

What makes one user go to /usr/lib/firefox instead of mozilla?
