Rated 5 out of 5 stars

maybe I stick with this add-ons for above 8 years. undo close tab is a smart feature I use often.
it backup my opened tabs even though Windows crashed!
this help me save time do not want to re-open website.
also I put saved sessions located on Dropbox this save my life.

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