Since updating to 2025.10 I notice reproducable crashing in Firefox on Android.

Firefox Desktop and Chrome Mobile/Desktop work just fine.
I already cleared the app data and even reinstalled firefox - no change.

Sometimes it's just the tab not working, sometimes the whole app needing a restart.

In the profiling you can see high CPU usage in the set CharacterData.data function.

To Reproduce
Steps to reproduce the behavior:

1. Login to Authentik (get redirected to User Homepage/Library) or naviage to authentik while already logged in
2. Tab/App becomes unresponsive on this screen:

Sometimes after a restart it shows the apps and works fine but a reload will trigger the bug again 100% of all tries.

Screenshots
I was able to capture a firefox profiling via USB Debugging:

• Deployment: docker-compose

Another Capture: https://share.firefox.dev/43zPCWh (I don't see the difference).

Worth noting is that the acutal login works.
SSO via any of the confiugred apps works without an issue.
Also (with an admin user) directly going to the admin console also works wihtout issues.
It must be something in the display of the library that breaks firefox.

Anything I can do to provide more information ?

I have a testuser I can provide, just not happy to post the url publicly.
Feel free to contact me via discord and I can provide url and credentials.
