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 try use Firefox Nightly, remove old version Firefox and install new version... but i still got the same problem.

I'm using Xubuntu 12.04 32 bits.

Please help me. Thank you.
