Hello,
I've tried everything, but unfortunately, neither the regular nor the Edge version of Firefox works for me. I'm running Home Assistant (version 2025.9.3) on a Raspberry Pi 4 with 8 GB of RAM. I access Home Assistant with the Companion app (version 2025.8.7-full). The first time I installed the Firefox add-on, it didn't work, and HomeAssistant wouldn't start after a complete restart. HomeAssistant only started again after a power cycle.
Now, regarding the problem: I installed the add-on, started it, and pressed the "Open Web UI" button. A black window opens, and I see three bars running, but nothing else. Even after waiting ten minutes, I still only see three bars running. I have also tried different resolutions, but unfortunately, that did not help.
Am I doing something wrong?
