Remember guys when the big bois* doesn't give a s about it's community project like this one come into rescue (yeah copy paste tho)

The best YT enhancer available. The user submitted database is surprisingly accurate, complete, and quickly updated.

I got this after purchasing Youtube Premium and being frustrated that YT were in violation of their contract to stop serving me ads. Now with SponsorBlock even embedded ads are gone.

Someone really needs to bring a class action suit against them, as Premium users should not need to find an FF extension just to fulfill YTs end of the contract for them.

game changer

No longer works with Firefox. Will just freeze the video when it gets to the sponsor section until you manually skip it. However even if it isn't working it's still better than nothing since it shows when the sponsor ends.

Doesn't work. Error 404. Sending a segment or setting a User ID gives a 404 error. In Chrome, it works without problems. It doesn't work in Firefox. Enabling VPN and proxy did not fix the error.
upd
It worked after (settings -> backup/restore -> reset default settings)

Не работает. Отправка сегмента или установка User ID выдаёт ошибку 404. В Хроме работает без проблем, в Firefox не работает. Танцы с бубном, VPN и proxy ни к чему не привели(
upd
Заработало после (settings -> backup/restore -> reset settings to default)

one of the best extensions

I really love this. Saves me from manually skipping those annoying sponsor segments. I pay for YT premium for a reason. If only there were a way to do this on mobile.

This is all i needed

Excellent QoL for YouTube, you won't even notice the sponsorship on the videos

Genuinely incredible.
