very simple and useful for songs only audio downloads, but hope there will be save as dialog for firefox soon...err...actually does not work at all, waiting animation displayed in place of button, i don't think this is interference of other extensions like ad blockers, useless, does not work

Does not work! The dialog box under video shows only "?" instead of file size, when trying to reload with all antitrackers disabled it only detects icon size ( 2kB) on all offered files.
The screanshots are out of date showing the earlier version and do not depicts the truth.
It was a great add-on when it was one exrension with audio converter and muxer which is mentioned and links are provided.
Gave a single star for developer to take more attention to what people say and fix the problems that seems to continue more than a year now!
