Sadly this doesn't appear to be maintained any longer. hls.js is only version 0.8.2 instead of the current 1.4.12
None of Apples example streams worked, so I guess this add-on is broken (I only tested Nightly 120)

doesn't playback video in FF (at least with playlist I had) but work in Chrome

I use it for a couple months on weekly basis. Very useful thing to use together with youtube-dl. It can even generate a command to run youtube-dl with all the arguments. Highly recommend.

doesn't work

no esta funcionando en las ultimas versiones de FF 84 aqui, en chrome no tengo ningun problema

hls.js 7.10 以降 radiko.jp でのストリーミング再生出来なくなっています

Will this work with .m3u extension?
