how to limit the number of tabs in the tabs bar
I would like to know if it is possible to limit the number of tabs that can be in the tabs bar. The reason is to reduce bandwidth use by any single user on my home network. Is there a way to set a max limit (under 10) in FF? If not is there an add-in that is capable of this task?
Also can FF be set to only open one copy of the program at a time?
