### `default-browser-agent` (Windows only)
On Windows, Mozilla [collects information](https://techdows.com/2020/04/what-is-firefox-default-browser-agent-and-how-to-disable-it.html) on what you've set as your default browser. However, disabling `default-browser-agent.enabled` also breaks the `Make Default...` button to set Firefox as the default browser.
Add it to your overrides if you do not use this part of the UI (or already have Firefox set as the default browser).

### Hide cross-site referrer
### Cross-origin referrer
Do not send a [referer](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Referer) when navigating to a different site (e.g., `google.com` → `facebook.com`).
For subresources, the referrer will only be sent to subdomains (e.g., `a.example.com` → `b.example.com`).
