Browser themes
Since the latest update my screen comes up black background with white writing (DARK theme). Even changing theme and saving, bookmarks, history etc still have black background. If I shut FF and restart it, everything defaults to DARK theme. Hard to read and annoying. Is this a bug or how can I change permanently? Regards, Richard Ferguson.

If that doesn't solve the issue, there is userChrome.css. Another user obtained partial success using autoconfig: https://support.mozilla.org/en-US/questions/1366357
