Some settings are controlled by an extension
If a setting says it’s controlled by an extension, a browser add-on has taken ownership of that preference.
Restore control
Section titled “Restore control”- Open Menu > Add-ons and themes > Extensions.
- Find the extension listed next to the message.
- Click the three‑dot menu and disable or remove it.
- Return to Settings and adjust the preference.
Notes:
- Some extensions change your Home page, New Tab page, search settings, or proxy settings.
- If you trust the extension, you can keep it enabled and configure options within the extension instead.
