Rated 5 out of 5 stars

OK, 5 stars to cheer you up so you give us all a happy Xmas by fixing it as it is so useful (Not working on FF26 + Win8.1) ... please!

This review is for a previous version of the add-on (3.5.0.1-signed). 

Thanks for your rating. Version 3.5.1 is being worked on. :-) I hope I'll manage to find and squash that issue. It doesn't happen for me.

I doubt I can do it by Christmas; but if you haven't yet, feel free to drop me a PM or e-mail so you can test the latest beta.
