A BrowserSetting object that can be used to change the browser's proxy settings.

Note: The ability to change proxy settings requires private window access because proxy settings affect both private and non-private windows. Therefore, if an extension has not been granted private window permission, calls to proxy.settings.set() will throw an exception.

The underlying value is an object with the properties listed below.

When setting this object, all properties are optional. Note that any properties that are omitted will be reset to their default value.

boolean. Do not prompt for authentication if the password is saved. Defaults to false.

ftpOptional Deprecated
