Browsers have a built-in "Clear History" feature, which enables the user to clear various types of browsing data. This has a UI that enables the user to select what type of data to remove (e.g. history, downloads, ...) and how far back in time to remove data.
This function returns the current value of these settings.
Note that not all data types will always be removable through the UI, and some UI options may map to more than one data type.
This is an asynchronous function that returns a Promise
.
Syntax
var getSettings = browser.browsingData.settings()
Parameters
None.
Return value
A Promise
that will be fulfilled with an object containing the settings information. This object has three properties:
options
. AbrowsingData.RemovalOptions
RemovalOptions
object describing the removal options currently selected.dataToRemove
. This will contain a property for every data type that can be toggled in the browser's UI. Each property will have a value ofbrowsingData.DataTypeSet
true
if that type is selected for removal andfalse
otherwise.dataRemovalPermitted
. This will contain a property for every data type that can be toggled in the browser's UI. Each will have a value ofbrowsingData.DataTypeSet
true
if the administrator of the device has allowed the user to remove that type, andfalse
otherwise.
If any error occurs, the promise will be rejected with an error message.
