Bug description:
When switching apps (with alt-tab, or clicking the Launcher) *to*
Firefox, Firefox crashes.
This does not occur for a while after reboot. However, once the first
crash has happened, a restarted Firefox will reliably continue to
crash every time it is switched *to*. So, starting Firefox works;
restoring the previous session works; navigating around, choosing
different tabs, adding new tabs works. Switching away from Firefox
works. However, switching back to Firefox causes it to crash every
time.
A reboot cures the problem (until it starts again).
Crash report sent to Mozilla (about a zillion times) and should be
therefore attached to this bug by apport, but if not: https://crash-
stats.mozilla.com/report/index/bp-dbbaef36-287e-4e2b-85bd-4ef8e2120810
Disabling Firebug seems to have cured the problem.
[SRU justification]
Looking through Mozilla's crash database, we're currently responsible for
about 1500 crash reports per week (taking in to account the different
variations of this trace), second only to Flash

[Test case]
- Update Firefox, perform whatever steps were necessary to trigger the crash
before (this could be opening the HUD, opening the menus, switching focus to
Firefox or just starting it - this really depends on which way the wind is
blowing) and verify it doesn't crash
[Regression Potential]
- None, it's just a null pointer check and another small change to ensure
that menus are disposed of fully to avoid leaving duplicated (and orphaned)
entries in the Firebug menu
