Review for Lightweight Themes Manager by jema888
Rated 5 out of 5 stars
This add-on is awesome. I have so many personas loaded into Firefox (over 400) that I cannot open my "appearance" screen as it just freezes. So I could never see exactly which personas were in there, nor could I delete any. With this add-on, I can see every persona I have loaded, and delete as I please. Wonderful!
