I just upgraded to FF5 and this add-in "Duplicate This Tab" was flagged as not compatible and was disabled. As per other user's suggestion I looked at Add-on Compatibility Reporter but since it is "Recommended for alpha and beta users only!" I decided not to use it as I'm not in that arena for my browser. At this point I will be evaluating other tab duplicators or consider switching back to MSIE which has native tab duplication capability.This review is for a previous version of the add-on (1.2.1-signed.1-signed). This user has a previous review of this add-on.
