Twitch is the same way, but youtube is working fine. Hexbear loaded correctly when I first installed this distro, then it just stopped working the next day without anything being changed.
I remember seeing someone else mention a similar problem a while back, but I couldn't find that post when I tried searching for it.
This is just a long shot but can you try reproducing the issue on the flatpak version of Firefox?
That seems to work, thanks.
Common flatpak W. I'm glad to have helped.
