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The screanshots are out of date showing the earlier version and do not depicts the truth.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!
