Uninstalled FF and reinstalled, that worked. Interestingly I do not have this issue on my dualboot Ubuntu FF.

I did purge my cache on Ublock, not working for me.

I don’t think they did a proper cost-benefit analysis for this one. Feels like the new CEO learned of ad blockers and put down a diktat.

I’m getting the pop-up, which I can click to close and watch videos on my FF + Ublock.
