I disagree; it works fine on our machines.
The only niggle is that you need to uninstall 64 bits java and reinstall 
32
bits (since the 64 bits install seems to overwrite the 32 bit one in part
s).
That also means everything that depends on it, which can be painful.
I also have modified the /usr/bin/firefox start-up script so that it look
s
in the right place for the plugin directories; by default it wraps the 32

bit plugins for the 64 bits version/
