Firefox Theme "switches" after startup

more options

I have this theme installed in my firefox browser (95.0.2). https://addons.mozilla.org/en-US/firefox/addon/arctic-nord-theme/

When the browser starts, the theme works for a second, then swithes to some darker theme automatically. If I go to Preferences and disable, then enable the theme again, it work as expectet. I have set `layout.css.prefers-color-scheme.content-override` to `1` hoping that it would pin the light theme, but it has no effect on the issue.

How can I make firefox not change to some dark theme on startup?

Not able to replicate the issue with my distro version of Firefox. see screenshot I was able to restart the browser and the theme was still there. Have you tried running Firefox in Safe Mode and trying the same steps? Try downloading another copy of Firefox and run it from the folder. Do not sign into your Firefox account and see if you have the same issue.

I am using Wayland. The problem seems to be related do the Profile, it does not reproduce on a fresh profile. My browser is never logged in.

So it works on the Firefox that you downloaded? Can you try the same steps in X11 with the Distro version and the downloaded version?

No, it works on the Distro version with a fresh profile.
