i use ublock origin

reddit still good for something: Filter Lists-->uBlock filters-->uncheck the "ublock filters - quickfixes" box and then reload the page.

this worked for me

Fuck reddit, this solution did not work for me. All YouTube videos stop buffering after 59 seconds. Only fixes i have found is with either making a custom userscript or disabling ublock from working on YouTube by whitelisting the entire domain.
