This extension is mainly for downloading music and videos, as most of them are streamed in chunks and can't be downloaded usually by just doing a right click and downloading it via the browser.

If you want the add-on to stop detecting only media, you can uncheck both boxes in the add-on settings, under "Detection method" to show all the requests, but it can load a very large list as it will load documents but also page source code and JavaScript files, etc, so it's not really optimized for that.

There is another add-on that also can do that for documents and other types of files, it's called DownThemAll, you can try it at https://www.downthemall.org/ (not my extension)
