Multiple Addon Deactivator is a Firefox extension, deactivate more than one addon at a time.
With this add-on, you can (de)activate one, many or all add-ons, at the same time. Very useful when you want to test addons or functions to see whether one or more addons make errors with webpages or with other addons.
Now you dont have to click on each deactivate link. You can check each add-on, you can check ALL add-ons or you can say, I will deactivate all + restart firefox or I will activate all + restart firefox. Thats very useful and easy.
It shows activated, deactivated and incompatible add-ons (who cant activated when they are incompatible with other add-ons or with the firefox version.)
You can set one option that will M.A.D. activated when you say deactivate all add-ons. Thats outstanding cause you can work with M.A.D. when you have deactivate all add-ons.
