Rated 4 out of 5 stars

Same as "monzter delapanbelas" below: Since few days tabs are lost after firefox restart. I was on FF 23, updated to FF 28, nothing changed. Installed Session Manager 0.8.1.1 but nothing changed again.
Please fix it !

This review is for a previous version of the add-on (0.4.1.3.1.1-signed).
