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!

its really cool but lacks the popout feature that is buildinto firefox. really missing that.

edit: never mind its still accesable trough Shift+Richtclick take my 5 stars

excellent job please increase buffer past 90

Doesn't work with VOD's :(

Amazing extension! It runs 100x better!

Жаль он не воспроизводит VOD'ы с твича.

Works great. I'd rather sit in silence than have to listen to horrible loud ads. Sometimes I leave streams open while I am sleeping.

One issue I've noticed, is that even when the volume slider is all the way down, it does not fully mute the volume.

Doesn't work anymore. Was amazing when it did work.

thanks for fixing

NOT WORKING anymore!

Stopped working as of 5/21/2021, player blocked by website

Even when not used, CPU skyrocketing to 50%. Mining ?

It works GREAT when it actually shows up on the site, recently it just disappeared from the site and until that is fixed its just a 3 star review because when it works its 5/5 stars

EDIT: Works in new update, hopefully it stays working, 5 stars since its working

Used to work great until today, the button on the top right to switch to the player doesn't appear anymore.

Temp fix : go to your extensions > cogwheel top right > debug extensions > scroll to the Alternative Twitch player and click the manifest URL> replace /manifest.json by /player.html?channel=
This should work for now

not working anymore. Working fine yesterday

Fixes my buffering issues and adds a slew of features. Thanks for fixing it!

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

Great improvement over the Vanilla Twitch player. Notably good to get rid of ads, and for the possibilities given to tweak video buffering and all just like you want.

I just wish there was a way to force the UI to remain visible at all time (currently, if I move my mouse out of the video panel, things like the pause button get immediately hidden).

Edit: thanks for your superfast reply. That wasn't really my question though, pause was just an example for illustration, the thing is I just want to keep the whole UI visible at all time. That being said, apart from this minor point, the extension is AMAZING. Can't believe I've been able to bear Twitch without it before, it's a life-changer. Thanks.
