Very useful, with a well designed interface Rated 5 out of 5 stars
This add-on saved me a lot of time when I was downloading an audio book that had 58 chapter links.
i.e. the other way to do this would have been to do 58 separate downloads by right clicking on the link for each chapter, which is slow, boring and error prone.
DownThemAll has a simple, intuitive interface which makes downloading easy and less error prone. I especially like the options that allows only the required file types on a page to be downloaded, e.g. Only download the mp3 links and ignore image files etc.
