People, don't give one star just because google wants to screw us with a new way.
This add-on is very good and deserves 5 stars. Just give developers time to find a solution and implement it in future updates.

YouTube ads just started appearing again, but as someone already suggested, uninstalling and reinstalling the plugin seems to resolve the issue (so far).
Fork Google.

This addon literally saved my life. Now that it's stopped working (on youtube), I'm instantly spiraling into uncontrollable depression after just 2 hours of exposure to ads. Patiently waiting for devs to send help.

This is amazing. If you are experiencing slip through ads especially on youtube, UNINSTALL AND REINSTALL the add on! <3 Thank you

9/10 this worked great and is a must use for the longest time but for some reason recently ads have been slipping through on youtube and some other unscrupulous websites
