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.


let 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

BCD tables only load in the browser


let downloadId = 2;

function onResumed() {
  console.log(`Resumed download`);

function onError(error) {
  console.log(`Error: ${error}`);

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

Note: This API is based on Chromium's chrome.downloads API.
