Improves stream quality and stuttering on twitch and removes advertisements.

To anyone whose chat is not working: Allow "https://twitch.tv" in the cookie exceptions in Firefox. Make sure you use https instead of only http!
-1 star because I had to crawl through help menu in the addon instead of this being in the description on this site here. Also for the unprofessional developer response (after more than a month) "do not cry. read the help instead. LOL" instead of just giving a straight answer.

-1 star because the mouse cursor still always disappears which is REALLY annoying.

EDIT:
-1 star because the mouse cursor STILL disappears 4 years later. AT LEAST ADD AN OPTION TO ALWAYS KEEP IT VISIBLE!

only for live and not for past broadcasts? (at least it doesn't work for me)

I have updated the app and dumped my cookies. I can't get it to stop playing ads on firefox browser.

Расширение останавливает воспроизведение на блокировку рекламы, даже если реклама на стриме отстуствует.

it was good for 2 weeks, and then now the ads aren't blocked. Ads are back again

It's a completely scuffed experience.

It completely changes the stream's layout, making basically a worse looking forced theather mode: you can't therefore look the stream info or other elements like sub button, or the streams list sidebar.

It also adds a very noticeable delay in the stream, something not really welcome when you want to interact with the stream.

It also breaks Picture in Picture.

Comments keep getting back to old position, and you have to scroll everytime to see the new comments on stream if you press C while in full screen.

Refusal to publish release notes here.

all of a sudden the chat panel is white and tells me to click login and open an external window. when i do it just goes doesn't work and i can't chat at all. tried reinstall.

BUG: There is black screen when i hover over any button from a extension. The screen freezes but the sound still playing.

Couldn't find a way to scroll down the page to see the streamer's info other than disable this addon

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.
