Had an issue with the new update, so I sent feedback through the player. Less than an hour later got a reply email that it was fixed, and haven't had anymore problems. Kinda surprised how fast this guy's on top of things, don't see that too often.

Great player. There was a small blip but as mentioned in the reply the dev has released a new version that stops the prerolls! Good work mate. 5star

I love it ! Would it be possible to use it for VODs in the future ? It would be so great !

Can we get support of the FFz audio compressor? and the hotkey sheets somewhere? Ctrl + shift +] doesn't work on macOS either

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.

Great extension, adds noticable stream delay though. Also wish it was possible to disable/rebind the F1 hotkey, I use that key for another extension and this one overrides it.

Great extension, only issue is the slight additional stream delay. Otherwise no problems

Doesn't work with Twitch Channel Points Auto Clicker?

I'm not sure how to get in touch with the dev of this app other than leaving a review. Overall, this extension has made Twitch an actually usable site for me. I have pretty good internet for where I live (400Mb Down, 50 Up). But, for some reason, Twitch constantly had issues. Streams would buffer, I would constantly get error 2k and error 3k codes where the site just legit gives up on trying to keep me connected. The most annoying thing is the fact that Twitch is now embedding ads into the middle of streams, disregarding what's going on and bypassing traditional addons that were normally blocked as an element of the page I assume. Alt Player legitimately erased all of those issues. I can watch a stream with no buffering and only a slight delay between chat and the stream. I Just wanted to share some issues I've been having recently with the extension that I'm sure are more to do with Twitch and Firefox than they are to do with the extension. As of today (09/23/2020) I'm getting streamer run ads and I think, Twitch ads inside alt player. As other people have mentioned I'm also experiencing the extension crashing and breaking until firefox is restarted. I assume this has to do with the firefox 80 update and not the extension. Great addon overall though. Wanted to just see if there was a way to get in touch with the dev but, since its a review, I thought it deserved a full one.

Unfortunately doesn't remove twitch ads anymore :(

Update: fixed after a few days! Love this extension!

Over the past week or so I've noticed FF tabs crashing a lot more. If I refresh the tab in question the stream will come back, but opening another stream in another tab doesn't seem to activate the addon again. I have to close FF entirely and restart for it to work properly. Which isn't ideal.

Edit: Thanks for the response. Does that bug also account for the addon saying that the "Broadcast ended" for streams that are actually live? Or it that something different.

Stopped working for me but was good when it did

If I input " :-) " in chat box, will make it disappear.

works great, just wondering if FF's native PiP could supported

Thanks for update

Wonderful app. Fixes buffering issues I had when the chat goes wild, and the audio never becomes distorted. Very clean player. However, it's buggy. It crashes often if I leave it running when a stream ends.

Works great. I can see my energy impact is more than halved in about:performance after switching to this. My request: Can you build a bonus channel points auto clicker embedded in the player or make it so that those kind of extensions work with your extension. Thanks a lot.

since today this add-on stops working.Twitch URL doesn't change. I can still use this on chrome tho.
PS:User Agent Switcher may cause this issue.I changed it to Firefox and it works fine.

I can't get my latency below 5-6 seconds even with the best settings available, while Normal Twitch Player has a 1 to 2 seconds delay in low latency mode.
Other than that, the extension is very good. Highly recommended if you have a low-end system because the CPU and RAM usage will be very low compared to normal Twitch Player.
