[throwaadblock]

I'm on firefox as well. It seems like maybe they are to some extent A/B ing this.

They gave me 3 warnings over a period of a few weeks and then finally stopped playing videos unless I disabled uBlock for the site

One thing to note is that I'm logged in.

Have you cleared cache and cookies? I was getting the message but clearing the browser seemed to reset the countdown.
