Ditto on all the requests for a version that will work with the new Firefox.

I will GLADLY donate.

I went here, downloaded the previous version of Firefox, got my session manager back!!

Will wait and hope for a new version of Session Manager.

This review is for a previous version of the add-on (0.8.1.13).
