Saves lot of resources Rated 5 out of 5 stars

I used to have hundreds of tabs open and used other add-ons to back them up. It was using a lot of resources. Now I'm using this add-on and it's fast, easy to backup, sync, and it's beautiful.
I hope they make it evn faster and lower on resources.
Thanks a lot!

This review is for a previous version of the add-on (4.1.6.1-signed).
