{{AddonSidebar()}}

The resume() function of the {{WebExtAPIRef("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.

Syntax

let resuming = browser.downloads.resume(
  downloadId      // integer
)

Parameters

• downloadId

  • : 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.

Examples

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);
