Rated 5 out of 5 stars

The add-on works very well, but I'm especially happy about the fact that I didn't have to actually come to the homepage to find out there was an issue with the YouTube's latest changes - I just opened the add-on and there was a message about the changes and a link to get the new version ... that alone is worth five stars! :)

This review is for a previous version of the add-on (1.5.1-signed). 

Thank you :)
In a future release I will add a function that will help users telling me what has changed on YouTube, this way I will be even more reactive.
