Used to work well, now twitch's updated ad code causes this add-on to cause a never ending black loading screen instead of the stream. It hasn't been updated to alleviate this as of late. Rating might change when it works again.

Update: Seems to finally have been updated and works again. Rating adjusted.

So glad this extension got forked and cleaned! Thank you for doing what's needed.

Current issue (June 2022): Twitch has (seemingly) removed access to quality of stream switching (if you look at the advanced settings, the quality options are actually missing) if you have this extension running. Once the extension is turned off, the quality options return and the twitch channel loads (with ads playing).

works well
