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."
