Great, except on Firefox 80 on Catalina it does not allow full screen on youtube. Perhaps youtube have recently changed something and it broke this? Clicking the fullscreen icon in the bottom corner of a video maximises the window size, but not the display size of the video, which stays the same size as previously. I will come back and change 3 stars to 5 if you can fix this, the addon is excellent otherwise (and I would have sent this as a private message rather than a review, to give you a chance to fix it, but I can't find contact info)

Edited to add: I am using this with a current version of uBlock Origin. Is it also possible to suppress the overlays that sometimes come up when you pause a video?

Absolutely fantastic add-on; I was searching for this type of feature for so long. And my quest ends with DF Youtube. You are a super awesome man; you nailed it. I really love it. I recommend this add-on to everyone on the internet.

Awesome, thanks a lot!

Excellent tool. Preferably remove it from the toolbar so you can't easily deactivate it

Awesome Awesome Awesome!!! This is exactly what I was looking for! I often lose large amounts of time in YouTube, and I while I have blacklisted it before I constantly have to go back for school related purposes.
I've tried blocking elements with U-Block with little success...
Then I found this Add-On! It is customizable and blocks all elements that you could want blocked, and is easy enough to toggle on and off. It's working great!

Retira diversas variáveis problemáticas do Youtube, tais como: recomendações de vídios, tela inicial etc. É excelente!

This is fantastic man, thanks for creating this. Youtube addiction is such a difficult beast to tame. The algorithm is so powerful!

THIS IS ABSOLUTELY PHENOMENAL! THANK YOU SO MUCH!!! :D
Finally I don't need to sink hours into youtube, while looking up some maths, or theories related to my undergrad

This is a brilliant extensions. I use it along with a reddit and facebook feed plugin and it sames so much time. Thank you

Hoping the developer sees this. Fantastic add-on. Just needs one more thing to be complete. A way to lock us out from changing the options as easily as we can right now. Please consider doing this- by means of password protection or lockdown times. Thanks again for your work.

Makes YouTube CLUTTER FREE!!
You control What YOU want to see

All features work great. For a while I did not know that I could click on it and access options but when I did discover that it became extremely useful. Thanks to the developers.
