First off - thank you for developing this add-on. It's saved my skin on so many occasions where the standard crash recovery system would have failed.

I really hope you will consider updating Session Manager for the new WebExtension add-on API in Firefox - which will break Session Manager from version 57 onwards.

Thanks again!
