TST & Tab Utilities Rated 5 out of 5 stars
If TST is installed with Tab Utilities Lite Custom or Tab Utilities Phoenix not all closed tabs are removed from the sessionstored.js and reappear on restart and can't be deleted unless one or the other addon is disabled. Try Closing tabs from tree's last tab. This was done on a clean profile on win 8.1 Fx 25.01. addendum: solution: browser.tabs.animate changed to false eliminates the problem.This review is for a previous version of the add-on (0.14.2013112901.1-signed).
