This add-on is a godsend for me. So far it works perfectly and it also doesn't seem to slow down Firefox.
I watch and listen to a lot of things on Youtube and I hate the way it tries to shove all that garbage down your throat: users' comments, often inappropriate or offensive, irrelevant recommendations or even relevant recommendations that steal your focus.
I don't mind too much having ads on useful content if it helps supporting the ones that produced it, but all that effort to keep you hooked and consume your concentration is intolerable and I believe it's even more heinous than on old regular TV: talk about progress.
I'll be using this add-on as long as it is maintained. Thanks a lot to the developers.

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.

Thank you very much for this awesome plugin, it's really great to finally see it on firefox and enabling me to stop procrastinating watching unimportant things on youtube and focus on whats important :)

It works well and it's simple to use.

It does not work in Firefox android. Can you fix that?

Thank you so much for this! I was afraid this extension wouldn't be available outside of the Chrome environment. I can speak for many people that will love using this add-on in the future. Cheers mate!
