finding and downloading the add-on was 'easy' but i am unable to get it running, or at least access to it.

Undecided yet, how do you auto resume downloads? That be helpful when sleeping

This app was perfect for accelerating downloads from fileshare services but now when I download videos the files don't save properly and halfway through they just turn blank.

This downloader is written purely in JavaScript hand there are no external dependencies. From Battlegrounds Png - https://www.battlegroundspng.com

Successful download, after having long searched how to launch this module, what is this idea of adorning it with an almost invisible icon! if we can't find it, how do you want to use it?
Not everyone uses a black or white theme!

Not impressed. Opens new FF download window for every file on a given page. 50 files? 50 windows! Nice try but did not save me much time.
