I had a problem with Firefox. When I start the firefox, it works. But for a while (randomly) I can't click on firefox menu anymore. The right click menu doesn't work either. The dropbox (select box) in website does not work.

I'm using Xubuntu 12.04 64 bits:

   Linux minh-desktop 3.2.0-26-generic #41-Ubuntu SMP Thu Jun 14 17:49:24 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux.

Everytime I get this problem, I have to restart the firefox. I had no problem with Firefox 12 had the problem with 13 and 14. I'm not sure if Firefox version or Linux Kernel causes the problem.

I tried safe mode but it doesn't help.

Please help. Thank you.

No, but disabling hardware acceleration.

Whoops. I meant to say that disabling hardware acceleration worked. The setting is under advanced preferences.
