This add-on is an application that helps you download and install content from the Internet. It will do that by using an Internet Download Manager (IDM). IDM is a native application that works on the Windows operating system. So, to be able to use it, you have to install it on your machine and then install the addon on your browser. You can do this by following the instructions found in the GitHub repository.

The add-on is compatible with any web browser that supports add-ons, such as Chrome, Safari, Internet Explorer, Firefox, Opera, and others. For example, if you are using Safari on a Mac, you will have to use Safari on Windows, too.
