when i klick the paste button a error occurs

"you need to edit your Mozilla config file to allow this action"

what i have to edit in Firefox?
any ideas?

edit:
it works in the quick reply with right click/paste
but not in in the normal reply mode, there is no paste in my right click menue

Instead of right click / paste try pressing CTRL+V together instead
