Comment 6 for bug 1035305

This bug was fixed in the package firefox - 15.0~b4+build1-0ubuntu1

---------------
firefox (15.0~b4+build1-0ubuntu1) quantal; urgency=low

  * New upstream release from the beta channel (FIREFOX_15_0b4_BUILD1)

  * Update globalmenu-extension to 3.4 prerelease r435
    + Drop the edit UI workarounds
    + Fixes for LP: #1035305 - Crash when switching apps back to Firefox
      with Firebug installed
      - Keep the menu we export in sync with the document tree all of the
        time, rather than only when the menus are on screen. The HUD likes to
        open submenus without opening any of its ancestors, which can result in
        us handling events on menu nodes that are no longer in a document
        if an ancestor responds to a bubbled-up event by removing its
        children
      - Ensure we always null check the result of nsIDocument::GetCurrentDoc
    + When tearing down a menu, make sure that we empty out our DbusmenuMenuitem
      in case the parent reuses that item for another menu. Fixes a memory leak
      and an issue where Firebug menu items are duplicated indefinitely each
      time a menu is opened
