@pieleric: I confirm it has gotten worse in 13.10. The BookmarkMenuHider didn't do anything for me, probably because most of my bookmarks are sorted and thus still in the menu. after installing the addon. The ui.use_unity_menubar trick did it, but I agree it is a pity it also disables HUD completely. Ideally the bookmarks should not be exposed to HUD, as they are already accessible through Firefox address bar (Ctrl+L).

It can take 3-8 seconds to change *tab*. During this time the CPU is maxed out; typical output from 'top' during this period shows 'hud- service' and 'unity-panel-service' combined using about the same CPU as Firefox itself: 100 10.4 26:07.73 firefox 53 0.6 6:14.86 hud-service 38 1.5 6:42.14 unity-panel-service I suspect that the change is causing a (an inefficient) re-index related to updated menu structures. (Eg. something like the history menu, although I can't see what it is as don't currently have a menu bar).
