LibreWolf blocking Peacock (and other streaming sites)

I recently dumped Edge and Chrome and ventured into the area of Brave and now LibreWolf as I do like the less round UI of Firefox more. I do understand that certain aspects of LibreWolf will break sites but I'm wondering if there's a setting in the about:config I missed in regards to getting PeacockTV or HBO Max for example to work. When going there on Brave it works fine, but on LibreWolf, Peacock for example says: "Sorry your system configuration is not compatible with Peacock" and HBO Max just says "unavailable". I've enabled DRM as well, but surprisingly, Paramount Plus works completely fine.

I've asked on the LibreWolf subreddit and didn't get much help, so even the smallest help, or a direction I can go would be appreciated as while I'm not un-tech savvy, this has beaten me. I've messed with the Resist.Fingerprint, WebGL and a few other settings in hopes of finding the culprit, but so far I've been unable to. I don't really have a problem using Libre as my main browser and Brave when I want to watch something.

Update: After using various friends accounts, I've been able to check out that Paramount Plus, Disney Plus and Hulu all work fine. Netflix, Max and PeacockTV do not. I hope this helps!

Frankly, the root cause of your problem is using a niche browser that is obviously not adequate for your requirements.

The leading browsers lead because they are reliable.

You can bash your head around trying to find solutions but that is only sticking plaster (imo).

The main reason I stick to the big guns is that I know they are well supported, particularly from security vulnerabilities.

Can you say same about Librewolf?

I don't use your browser, but have you tried masquerading the UserAgent?

Yeh, I've tried LibreWolf but fails in so many ways.

Bit too early in its development to get too excited about it. At the moment, its designed to serve a purpose, albeit still limited for general use.
