Rated 4 out of 5 stars

This is a good start on a solution to a pressing problem. I have a *lot* of extensions, but I don't want to use all of them, all the time. For instance, I use the wonderful Firebug web development debugger tool. Firebug has a number of extensions designed to be used with it. I either want all of them, or none.

Right now I have different profiles customized for different purposes, and the differences are just which set of extensions are loaded.

I would *really* love the ability in a future release to classify extensions into groups, give the groups names, and enable or disable the entire group by name. This would potentially let me consolidate multiple profiles into one, by simply checking what group(s) I wanted active and restarting FF if I needed to change activities.

This review is for a previous version of the add-on (1.1.1-signed.1-signed). 

Thx for your feedback.
It is a nice idea, but thats a big change for M.A.D. When it comes, so it will not comes in the near future and only for a new mainversion like 2.0. Why? Its only a feature request from one guy. When this feature is desired by several people, than I will leave a thought on it. But now I have only make a note of my todo list with a low priority, sry.
