Rated 4 out of 5 stars
Found bug with tab order of recenly closed and restored windows. Open new window and several tabs in it (ex:Google, Facebook, Newgrounds, Wikipedia), close and restore it through "History > Recently Closed Windows". All tabs but the first one became reversed: Google, Wikipedia, Newgrounds, Facebook. Same happens in Session Manager extension when appending loaded session to the current one. Using Firefox 16.This review is for a previous version of the add-on (1.2.1-signed).
