Clears any local storage created by websites.
You can use the removalOptions parameter, which is a browsingData.RemovalOptions object, to:
- clear only local storage objects created after a given time
- control whether to clear only local storage objects created by normal web pages or to clear objects created by hosted apps and extensions as well.
This is an asynchronous function that returns a Promise.
Syntax
var removing = browser.browsingData.removeLocalStorage( removalOptions // RemovalOptions object )
Parameters
removalOptionsobject. AbrowsingData.RemovalOptionsobject, which may be used to clear only local storage objects created by normal web pages or to clear objects created by hosted apps and extensions as well.
Return value
A Promise that will be fulfilled with no arguments when the removal has finished. If any error occurs, the promise will be rejected with an error message.
