# Firefox – How to have Firebug only open in one tab

firebugfirefox

When I bring up the Firebug control panel in one tab on my browser, it is also activated in all other tabs. So if there is only one tab I'm debugging, any time I switch away from that tab I have to hide Firebug, and every time I come back to that tab, I have to re-show it.

These tabs are NOT on the same URL, and the Firebug option "activate for same origin URL's" doesn't seem to do a thing anyway since mine is automatically in a mode which I am naming "activate for ALL URL's."

Firefox 19.0.2, Firebug 1.11.2, Win7 x64

Go to about:config and set the preference extensions.firebug.allPagesActivation to none
