The default player makes my computer heat up immediately, but I've had no issues at all with this player, it works great! The only thing I'd like is the ability to use it with VODs as well.

Wasnt having any problems until recently where it seems to log me out of chat while in it, i close out of it and im logged in, back in and im logged out again, and cant seem to watch it and be logged into chat.

Edit: Nvm figured it out myself, Privacy Badger was causing problems with it.

Fixed my stuttering on Firefox. Thank you so much. Set my simultaneous downloads to 3 under buffering.

Wonderful.
I've been using this addon for a long time.
If it stops working, it's because Twitch changed something.. Give the lone developer a day or 2 to fix things.
VERY consistent and dedicated dev here.
I love this addon

saved me from persistently black/ not loading videos for twitch live under firefox 63.0.1

Thank you so much!

10/10 ! For people ask for the broken chat >>

"If you have problems with chat, then open your browser settings and allow to accept cookies, including third-party cookies, or add an address https://twitch.tv to exceptions. If this does not help, try to select a different chat version in the player settings. Also, chat can be broken by: other browser extensions, ad blockers, firewalls, antiviruses. To diagnose the problem, try turning off all this shit. Here are the Privacy Badger extension settings, which do not interfere with chat."
