Comment 18 for bug 968533

I've been having some pretty bad firefox performance issues in 13.10, even in safe mode. It seems that if I disable the the global menu with this (in about:config):
ui.use_unity_menubar = false

then restart, performance is *greatly* improved. unity-panel-service and hud do not peg the CPU any more. Not sure why this was worse from me (guessing something in 23?) but now I can change tabs, load page, use the menu and the browser is snappy.
