> [!NOTE]
> - **navigator.webdriver** is set to false at all times.
> - `navigator.language` & `navigator.languages` will fall back to the `locale:language`/`locale:region` values if not set.
> - When spoofing Chrome fingerprints, the following may leak:
>   - navigator.userAgentData missing.
>   - navigator.deviceMemory missing.
> - Changing the presented Firefox version can be detected by some testing websites, but typically will not flag production WAFs.
