I used it only because it was the only solution to ads for me. Now it shows ads so it's pointless to use with inferior features to twitch's website.

used it to block ads, it no longer does this. pointless now.

It used to work like a charm for me, but suddenly I've started getting advertisements on the streams again, I tried to watch a stream earlier and still got some dumb samsung phone ad instead. Even after updating this still occurs.

It also doesn't auto start for me anymore, I have to manually click the twitch5 icon every time.

EDIT: Yep, literally every stream I try to go to plays an ad now.

EDIT2: It's another change that twitch made with their preroll ads. Look twitch, I don't hate all ads, just the cancerous preroll ones.

EDIT3 if people were using this for ad blocking, consider this. https://github.com/instance01/Twitch-HLS-AdBlock

not BTTV compatible (the BTTV settings link is not visible)
not "clips" compatible
not vod compatible, so unusable for past episodes
cant view "panels"
cant use extensions

if you only want to watch and never interact, its fine

It worked great when I first got it. Although with the developers genius new update, it no longer works. Left click to start extension? Right click to auto start. Neither work. 10/10 update.

Update: Works on live stream, NO LONGER works on pre recorded twitch vids. You get spammed with the same commercial every 2 minutes, while watching a recorded stream lol... 100% intolerable.
