The cancel() function of the downloads API cancels a download. The call will fail if the download is not active: for example, because it has completed downloading.
This is an asynchronous function that returns a Promise.
Syntax
var canceling = browser.downloads.cancel( downloadId // integer )
Parameters
downloadIdinteger. The id of the download to cancel.
Return value
A Promise. If the request was successful, the promise will be fulfilled with no arguments. If the request failed, the promise will be rejected with an error message.
