Not able to play DRM content on https://www.southparkstudios.com/

[anthonyabbasi]

BEFORE YOU BEGIN

I have attempted the following troubleshooting suggestions:

• [x] The issue persists when using Firefox in Troubleshoot Mode.
• [x] Disabled DNS-level content blocking (AdGuard Home, NextDNS, Control D, RethinkDNS, PiHole, etc), cleared my DNS cache, and used my ISP's DNS resolver (if applicable).
• [x] Cleared website data, restarted Firefox, and my issue persists.
• [x] I have created a new profile. The issue persists when using the current user.js file on GitHub. (Must be in a new profile and a new user.js!)

REPORT

Screenshots

Desktop (please complete the following information):

• OS: Windows 11 Pro 23H2
• Browser: Firefox

Additional context I tried changing the google widevine plugin from 'default' to 'enabled' and 'disabled' but that didn't fix anything I am currently using the base user.js file with the following added overrides:

I am able to reproduce. However, if I disable uBO, it works. Did you rule out that this was an adblock issue?

[yokoffing]

The video plays for me if I allow cdn.privacy.paramount.com https://github.com/yokoffing/filterlists/commit/5af3fc09c303eab90220343de1dcbed79c83f2b7

[anthonyabbasi]

Yes, the video doesn't play even when I disable uBO (I'm using enhanced filter lists) and also when i go troubleshooting mode. I just disabled the enhanced tracker protection built into firefox and realised that was the actual issue, I'm sorry that I didn't try this before. Below is the sites the enhanced tracking protection blocks if you can somehow fix it on your end. I doubt the issue is with the https://js-agent.newrelic.com as uBO already blocks this and I've tried on a new profile with uBO only installed and the video works perfectly.

I didn't disable ETP to get it to work. In fact, my Firefox is blocking more than those requests:

fwmrm.net doesn't appear at all.

Can you disable gfx.canvas.accelerated to see if that changes anything?

I've tried on a new profile with uBO only installed and the video works perfectly.

What about a new profile + user.js (not overrides) + uBO?

I have tried this but the issue still persists.

Yeah I've tried this and it works fine, I reported the issue as broken on the Enhanced Tracker Protection popout.

[yokoffing]

Ok. Sometimes different requests are served based on one's location.
