Rated 3 out of 5 stars

Pros: A very compact and customizable add-on. You can make the design very minimal and achieve the same information any download manager would give you, such as using small texts and custom color codes.

Cons: THE ONLY con which makes this add-on so aggravating is the animation when the download clears itself, or even if you manually clear it. Animated gifs get choppy, switching tabs takes a noticeably long time, the context menu takes a while to come up; the whole browser just slows down and I have a very up-to-date computer
Having an option to turn off animations would make this add-on absolutely perfect, but I have been waiting a while for that feature and nothing is coming up.
