I’m running into an issue accessing the Jellyfin web UI from Firefox (Chrome works fine). I try to log into an account but the spinner runs for a few seconds then disappears without logging in. When I reload the page, it appears I’m logged in, though all I see is the header and the rest of the page is blank. I get the following errors in console:

Uncaught Error: Permission denied to access property "ownerDocument"
Uncaught Error: Permission denied to access property "localName"

Has anyone else run into this issue?
