Rated 5 out of 5 stars

---One possible improvement:
when I do Tools, Themeswitcher and I move my mouse cursor over each of the personas listed, I would like to see each of these personas directly on my browser (as sometimes I do not remember how one persona looks like).

---IN OPTIONS, THERE IS THE OPTION “AUTOMATICALLY SWITCH EVERY X MINUTES” WHERE YOU CAN CHOOSE THE NUMBER OF MINUTES X.

---Conclusion: For me, this addon is perfect. It allows me to switch between my personas without having to log on to a site.
