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.
What distribution are you using and what Firefox version are you using (and in what format is it packaged in?)
You might want to tell us what is in your about:support page, specifically Application Basics. There's also a setting for refreshing firefox and clearing settings.
Linux Mint 21.3, and Firefox is version 121.0.1 with the build id 20240108143603, and is what came already installed in the distro.
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.
