Firefox functionality problems when globalmenu is installed

Oneiric i386 on thinkpad t42

If firefox-globalmenu is installed in the system, you cannot use "ctrl-t" for new tabs and not open the menu on right click in the bookmarks. Nothing happens when this keys are pressed. When removing firefox-globalmenu with synaptic everything works well.
