[Bug 775229] [NEW] Context menus are unstable

[LagartoFlojo]

Public bug reported:

Binary package hint: firefox

Sometimes, and arbitrarily, context menus will appear, but as soon as I hover my mouse over them, they disappear. This happens on and off, and restarting Firefox fixes it (for a while). When I'm having this problem, clicking on any folders on the Bookmarks Toolbar does not show the menu. I can still browse the menus using the keyboard arrows.
Menus affected: right click on the page, right click anywhere on the toolbar, the search provider menu, bookmarks toolbar menus.

Ubuntu 11.04.
Firefox 4.0.1+build1+nobinonly-0ubuntu0.11.04.1
firefox-globalmenu 4.0.1+build1+nobinonly-0ubuntu0.11.04.1
