Rated 5 out of 5 stars

Perfect for people who -like me- need to use multiple profiles to keep their private stuff seperate from their work. It works like a charm.
The only impovement I would like to see is an option to be able to show just the profiles when I click on the add-on bar 'icon'. So I do not have to open up a sub-menu (like how it works in Chrome).

This review is for a previous version of the add-on (1.4).
