Google ramps up its campaign against ad blockers on Chrome.
Google is transitioning Chrome's extension support from the Manifest V2 framework to the V3.
This means users won't be able to use uBlock Origin to block ads on Google Chrome.
However, there's a new iteration of the app — uBlock Origin Lite, which is Manifest V3 compliant but doesn't boast the original version's comprehensive ad-blocking features.
YouTube isn't playing on Firefox with Ublock for me either. I'll need to go through and reinstall my extensions, but I couldn't find the root cause so far, I'd just been using chrome with ublock for YouTube and Firefox for everything else.
Make sure jnn-pa.googleapis.com isn't blocked anywhere in your network. It may perhaps be blocked in a filter list you have activated in uBO, DNS, VPN, Firewall, anti-virus, Firefox enhanced tracking protection, etc.
