This add-on is fantastic with the exception of one important bug. On Firefox version 61.0.2 hiding the side bar also removes the skip add button so you have to either disable the DF add-on or watch the entire add.
Thanks for pointing this out! I have fixed this issue in the latest version. I also highly recommend the uBlock Origin add-on, which blocks ads across the web and makes YouTube video ads a thing of the past!
