Rated 5 out of 5 stars

I have only had the program for a very short while, but it I found it to be my favorite add-on. I was able to start Firefox, and automatically set my daily four tab layout, plus another instance of Firefox with a three tab layout. Previously, I had to do all of this manually, and without the tiled layouts!
Love at first sight!

This review is for a previous version of the add-on (8.5.1-signed).
