Excellent Rated 5 out of 5 stars

This is my favourite FireFox add-on and the developer is always very quick to update it when there are any changes in FireFox or YouTube etc.

To the other reviewers who take time to leave a negative review just becase the add-on is temporarily broken for a few days (likely because of changes outside the developer's control):

Making a donation to the developer is likely to get the issue resolved much quicker than leaving a demotivating review or comment.

Thank-you!

This review is for a previous version of the add-on (4.9.21).  This user has a previous review of this add-on.
