You can listen to the cookies.onChanged
event to be notified when cookies change. The listener is passed a changeInfo
object that contains a cause
property, whose value is the OnChangeCaused
string:
browser.cookies.onChanged.addListener(function(changeInfo) { console.log('Cookie changed: ' + '\n * Cookie: ' + JSON.stringify(changeInfo.cookie) + '\n * Cause: ' + changeInfo.cause + '\n * Removed: ' + changeInfo.removed); });
Note: This API is based on Chromium's chrome.cookies
API. This documentation is derived from cookies.json
in the Chromium code.
