get()

The BrowserSetting.get() method gets the current value of the browser setting, and an enumeration indicating how the setting's value is currently controlled.

This is an asynchronous function that returns a Promise.

Syntax

var getting = setting.get(
  details     // object
)

Parameters

details

An empty object.

Return value

A Promise that will be fulfilled with an object with the following properties:

value

The value of the setting. The type of this property is determined by the particular setting.

levelOfControl

string. This represents the way the setting is currently controlled. You can use it to check whether you can modify the setting. See BrowserSetting.set() for details. Its value may be any of the following:

"not_controllable"	Extensions are not allowed to modify this setting.
"controlled_by_other_extensions"	Another extension that was installed after this one has modified this setting.
"controllable_by_this_extension"	This extension is allowed to modify the setting.
"controlled_by_this_extension"	This extension has already modified the setting.

Browser compatibility

Example

Log the value and level of control for the networkPredictionEnabled property of the privacy.network object, for private browsing windows. Note that this requires the "privacy" browser permission.

var getting = browser.privacy.network.networkPredictionEnabled.get({});

getting.then((got) => {
  console.log(`Value: ${got.value}`);
  console.log(`Control: ${got.levelOfControl}`);
});
