So … after restarting my firefox 1 gazillion times testing all my add-ons… the each one added some time to launching of pop-up or tabs … but firebug was MASSIVE ... and it’s a shame as i really love it ...
My first inclination, was just to use the firebug built in “disable” ... but that only showed minor improvements …
So now i DISABLE it completely from the ADD-ON menu… and only have web developer which does most of what i need … and when i need to use firebug … i enable and restart my browser…
such a shame … try it and see …
