Livestreamer won't open [Opera]

[alluria]

Nothing happens when I click in "open in Livestreamer". Twitch Now is the only extension I have, so I think it's a bug In Firefox is working, tho.

Same in Chrome.

I just experienced the same. :/ I'm on linux and it doesn't seem to want to use it even tho it's located at /usr/bin/livestreamer.
