This method can work for any browser, as long as u have Tampermonkey, or similar extension installed. And I think this method recommended to people that using IDM. I haven't tried using other downloader.

• Check this link, and install this script: https://greasyfork.org/en/scripts/39504-%E7%99%BE%E5%BA%A6%E7%BD%91%E7%9B%98%E7%9B%B4%E6%8E%A5%E4%B8%8B%E8%BD%BD%E5%8A%A9%E6%89%8B-%E7%9B%B4%E9%93%BE%E5%8A%A0%E9%80%9F%E7%89%88
• All are explained on that page, but in Chinese, so better use translator. haha.

But I think I can help a little:

• This script add other download button on baidu page (if u familiar with baidu, u will notice the new button). With this new button, we can download using IDM.
• It would work if u login with Baidu or other supported account.
• The developer recommendation is add item that u want to download to your Baidu account, then download from your baidu page.
• If u download directly, click on most right download button, then choose the bottom option. It will showed few links, choose one and download using IDM, make sure to click "Start Download" after file size show.
• If u download from your baidu page, click on left download button, hover to API, and choose the second one from top option. It will showed few links, choose one and download using IDM, make sure to click "Start Download" after file size show.
