Here’s uBlock Origin’s official guide to bypassing youtube’s anti-adblock popups, updated weekly. Please share widely. Don’t reward google for their predatory anti-consumer bullshit
To summarize: 1. Get uBlock Origin and make sure it’s updated to the latest version. 2. Click on the gear icon to get to the dashboard, go to “Filter lists”, and make sure that “uBlock filters – Quick fixes” is up to date
Repeat those steps any time you get another popup (google and uBlock are having an arms race right now so it might stop working at any moment), and if you have any more problems, read the reddit thread for troubleshooting advice
