An empty "Menu" appears when FFChrome is installed

This is because that extension hides the menu normally by just using the CSS display attribute rather than the hidden attribute on the menu node. We don't look at the CSS display attribute, primarily because this would break a lot of menus for other reasons.

I wonder what happens on Max OSX. It must have exactly the same problem.

This is fixed here: http://bazaar.launchpad.net/~extension-hackers/globalmenu-extension/trunk/revision/376

This bug was fixed in the package firefox - 14.0~b9+build1-0ubuntu1

---------------
firefox (14.0~b9+build1-0ubuntu1) quantal; urgency=low

  * New upstream release from the beta channel (FIREFOX_14_0b9_BUILD1)

  [ Chris Coulson <email address hidden> ]
  * Update globalmenu-extension to 3.3 prerelease r386
    - Fix LP: #1016081 - Menubar is not hidden when using the Firefox
      button outside of Unity
    - Fix LP: #775305 - An empty menu appears when FFChrome is installed
    - Fix LP: #1017247 - Menubar appears in the window as well as the
      Unity panel. Manually register our UA stylesheet rather than relying
      on this happening via chrome registration, to work around a bug
      in various bootstrapped third party addons (eg, pentadactyl),
      which initialize and use the stylesheet service before extension
      chrome is registered for non-restartless addons such as ours
    - Add a small delay when opening the menu with the keyboard, so that
      the additional items are added before the menu appears. Fixes an
      issue where keyboard focus isn't on the first item when opening the
      history menu with the keyboard
  * Apport hook improvements:
    - Sort preferences alphabetically in the apport data
    - Treat preferences set in default addons as default prefs so that
      they don't show up in apport data, unless the preference files have
      been modified
    - Support random pref files dropped in to the Firefox install folder, and
      preferences from application bundles
    - Fix ordering issues when loading preferences
  * Fix LP: #1013171 - Fully support Python 3 in the apport hook
    - update debian/apport/source_firefox.py.in

  [ Martin Pitt <email address hidden> ]
  * Add partial support for Python 3 in the apport hook (LP: #1013171)
    - update debian/apport/source_firefox.py.in
