Review for Duplicate Tab by Noffe
Rated 5 out of 5 stars
I love this extension but I can't get it to work when I try to change so it works with FF 3.5.
I followed the guide at http://kb.mozillazine.org/Editing_an_add-on_to_change_its_compatibility.
But it say that Installation script is missing -204.
Can someone help or upload a working version please.
