The resume() function of the downloads API resumes a paused download. If the request was successful, the download will be unpaused and progress will resume. The resume() call will fail if the download is not active: for example, because it has finished downloading.

This is an asynchronous function that returns a Promise.


var resuming = browser.downloads.resume(
  downloadId      // integer



An integer representing the id of the download to resume.

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.

Browser compatibility

var resuming = browser.downloads.resume(downloadId);
resuming.then(onResumed, onError);
