If you do not keep changes after a restart or otherwise have problems with preferences, see:

The data of all installed lightweight themes (Personas) and its background color and text color is stored in the lightweightThemes.usedThemes pref in JSON object format ({"id":"#","name":"xxx",...}).

There is software like Advanced SystemCare with its Surfing Protection feature that can protect files in the Firefox profile folder against changes. If you have such software then check the settings or uninstall this software.
