Cannot Access Dashboard via Firefox

Configuration Frontend
1

Hello everyone,

I’m trying to repurpose two iPad 2 devices from my kids as dashboards for my Home Assistant setup. Unfortunately, the iPads are running an outdated iOS version, which prevents them from running the Home Assistant app or accessing the dashboard through Safari.

Setup:

  • Devices: iPad 2 (both)
  • Access Method: VNC connection to a VM running the latest version of Firefox

Issue: When I attempt to access the dashboard using Firefox on the VM, I encounter the following errors, and the dashboard fails to load:

What I’ve Tried:

  • Verified that Firefox on the VM is up to date.
  • Deleted, reloaded Cache
  • Restarted both the VM and Home Assistant server.

Questions:

  • Has anyone experienced similar issues with Firefox and Home Assistant dashboards?
  • Are there specific configurations or dependencies that might be missing?
  • Any suggestions on alternative approaches to display the dashboard on older devices?

Any help or pointers would be greatly appreciated!

Thank you!
