send-to-mpv (ubuntu14.05 + firefox 62) on youtube > fails to recognize file format

[mrkapqa]

Hello ,

i have installed your firefox add-on + linux script on my computer running kubuntu 14.05.x

when i check the conneciton it would say something like "native player detected"

but afterwards, if i would like to play a video through the add-on, there would always be an error, saying that mpv does not recognized the file format m3u8 or similar.

It would detect several links as shown in the number in the icon of the add-on, but i would just like it to play one video after all.

please see attached picture

thank you very much
