Absolutely the best Tab addon I've ever used. Best because it adds a "duplicate tab" BUTTON to your firefox that you can then put where you want it (using customize)

It is certainly a shame that development of this addon has been discontinued, but I changed the .xpi file to work up till version 9.9 as described by others. Thanks!
