This addon works flawlessly on my browser. It could capture any hls stream and list them all (because sometimes there are some stream for different resolution). I simply select on one to download.

Es funktioniert nicht

Did not work at all, just a waste of time!

For me (under Fedora Linux with an HLS file hosted by Akamai) it worked fine.

Did not work on any sites i tested it on.

Unfortunately doesn't work for the website I tried. It downloaded video, but no audio.
