Describe the bug

When LiveTL is enabled and in "embedded" mode, Youtube chat acts as if I am not logged in:

Steps To Reproduce

1. Set LiveTL to "embedded" mode
2. Visit a livestream
3. Observe missing chatbox, notification that one must have had been subscribed for x days before being able to chat, or a sign-in button that redirects to the Google sign in page and back to the stream, but does not change anything

Expected behavior

Ability to chat normally with LiveTL embedded in the chatbox

What browsers are you seeing the problem on?

Firefox

Anything else?

No response

IIRC from Discord, this happens if "Enhanced Tracking Protection" is on.
