If you are using the open source Firefox web browser to browse YouTube and watch its videos, then you might have noticed that there is an artificial delay
Google slows down Firefox users when watching YouTube....
@furycd001 I continue to use this extension in Edge Browser, page opening is slowed down a little but advertising is blocked. Greetings from Italy https://ublockorigin.com/
That is not their official website btw. The maintainer of uBO has stated that he doesn't want a website
He doesn't want a forum or a website, thus he won't have any costs and he won't have to accept donations meaning he doesn't have to deal with the administrative workload and that way he has more time to develop uBlock Origin.
