I am experiencing a similar issue on Ubuntu 12.04.2 LTS with KDE 4.10 installed and Firefox 20.0a2 (2013-02-10) (Aurora). After a while, right-click menus and those from extension will just draw a frame briefly and then disappear. Toggling HW accel in both Firefox, and kwin din not help. Also, starting Firefox with an empty profile did not help either.
