Thanks! Rated 5 out of 5 stars

I did the first advice, found how to do the second too (just added youtube.com in Listed Sites and unchecked Trust Listed Sites). Very useful add-on, I almost gave up I can find something that really blocks the comments in YT.

This review is for a previous version of the add-on (4.0.2).  This user has 2 previous reviews of this add-on.
