The theme doesn't apply to my Firefox settings.

I set the black theme, but when I reboot Firefox, the settings do not take effect.

Each time I have to go into the settings and set them again.

I need help. My eyes hurt.

Note: Some software, like Advanced SystemCare with Surfing Protection, can protect files in the Firefox profile folder against changes. If you have such software then check the settings or uninstall this software.
