CloseReview for Duplicate Tab by ol01
Rated 5 out of 5 stars
!! SUPER !! I like this add-on very very much. You can Duplicate the same Tab with all the history. You can work on 2 same tabs with the same browsing history! VERY HELPFUL FOR STUDENTS!
This review is for a previous version of the add-on (0.9.1).To create your own collections, you must have a Mozilla Add-ons account.
