looks like rendering adblockers extensions obsolete with manifest-v3 was not enough so now they try to implement DRM into the browser giving the ability to any website to refuse traffic to you if you don't run a complaint browser ( cough...firefox )
here is an article in hacker news since i'm sure they can explain this to you better than i.
and also some github docs
If they implement it in pure software, then it's easy to crack.
They're not going to wrap Chrome in Denuvo because that would ruin its performance. The last thing they want is for Firefox to be not only faster but dramatically faster. Performance is a big part of how Internet Explorer lost its market share. And even if they do wrap it in Denuvo, Empress will no doubt show them the error of their ways.
So yes, I expect they will use firmware/hardware, presumably TPM or Microsoft Pluton, to implement this.
