browserSettings
Enables an extension to modify certain global browser settings. Each property of this API is a BrowserSetting object, providing the ability to modify a particular setting.
Because these are global settings, it's possible for extensions to conflict. See the documentation for BrowserSetting.set() for details of how conflicts are handled.
To use this API, you need the "browserSettings" permission.
