This stupid (sorry) extension totally destroys after the latest update: a) Firefox's 20.0.1 last opened tabs session b) Firefox's 20.0.1 bookmarks toolbar (maybe something else). I lost an hour or so to discover that all these troubles were because of this buggy extension update

This review is for a previous version of the add-on (5.5.1-signed).
