good idea that works as advertised, but a little untidy Rated 4 out of 5 stars

It's good to have a way to toggle "restartless" addons off-and-on, on the fly without having to go to the addons manager page. This add-on creates a separate toggle button for each such add-on that you have, and you can drag some (or all) of these to a toolbar using "Customize". If you have a lot of addons it sort of clutters-up the Customize Toolbar button collection that you drag from. And if you drag more than a couple of them then it might clutter up your toolbar, too. Maybe better would be a button with a dropdown menu of add-ons that you can toggle. Or a submenu of the firefox main app button.

This review is for a previous version of the add-on (0.2).
