It's a very great addon. But it's damage that it's doesn't work correctly (bug) with the latest Nightly version of Firefox (20 & 21). Maybe you know that ? I hope you will fix it. I open a topic and this the link : https://forums.mozilla.org/addons/viewtopic.php?f=31&t=11805 .
Edit : Thanks for your answer. If you need more details, ask me. If I can answer, I will do it. Cheers.
Thanks for the feedback - I don't usually test on Nightly builds but I'll check it out and see what I can do. Cheers!
