dexter would be proud #1235

- just to be clear, this section is not supported: not interested in references or explanations or  FF version numbers or default info etc
- "do more harm than good" - ambiguous, not interested in explaining why exactly: but FYI
  - some leak
  - most break shit
  - almost all are easily fingerprinted and the combo of them would make you really stand out
- removed the duplicate `ui.prefersReducedMotion` - this should move to personal as well
- moved `ui.systemUsesDarkTheme` to personal
