cookies.set()
The set()
method of the cookies
API sets a cookie containing the specified cookie data. This method is equivalent to issuing an HTTP Set-Cookie
header during a request to a given URL.
The call succeeds only if you include the "cookies" API permission in your manifest.json file, as well as host permissions for the given URL specified in its manifest. The given URL also needs the necessary permissions to create a cookie with the given parameters.
This is an asynchronous function that returns a Promise
.
