Can you add a message bridge/API so I can inject my Twitch "SleepSafe Sound Audio Normalizer" into your player page, e.g. moz-extension://7a621ae0-f468-4129-8951-56d84d276e52/player.html?channel=streamer

Would be very nice, if you can make it possible. Thanks

Working perfectly. Thanks!

I tried a lot of things to solve the stuttering on firefox, this is the only thing that worked perfectly.

Works really well. Should have much higher rating. If you want to watch with the Twitch player, just click on the title on top. Easily solves annoying Twitch ads. Will play in lower resolution for the ad duration, but overall works more often than ublock origin (for twitch)

I've been enjoying the Alternate player for years & it works well than the default site, sadly it's getting destroyed by 1440p encryption. Hopefully it gets updated to deal with 1440p streams.

Was working quite well until recently, it will now infinitlely buffer while ads are playing instead of hiding them like usual. I would suggest finding an alternative, as the last update was some time ago.

Starting about a week ago, now when ads play, it freezes instead of lowering the quality until the ad is over.

This broadcast is encrypted. The Alternate Player for Twitch.tv extension does not support encrypted broadcasts. Click the “Back” button to return to the previous page.

It works well at blocking ads but the typing area in the chat window will no longer work as of last week. It was perfect before that.

Update: As of 11-30-25 its working for me with no problems.

Overall, a shady addon.

1. Addon has BSD license without source code linked.
2. It sends telemetry, unique persistent device fingerprint, device, screen, date and time, time zone, CPU, GPU, languages information when you try to send a report.
3. Contrary to its policy (coolcmd.github.io/privacy.html#tw5-en), you cannot refuse to include the data, only refuse to send the report altogether.
4. The server URL is not disclosed: r90354g8.beget.tech/tw5/report3.php
5. Chat in the extension page doesn't save theme across browser sessions.

EDIT: you can still see the extension's code in the browser, it's not minified. IT'S IN RUSSIAN (yes, the whole code, not just the comments).

```
if (!лБыстро) {
м_Преобразователь.Остановить();
м_Проигрыватель.Остановить();
м_Помойка.Сжечь();
}
м_Журнал.Окак('[Запускалка] Работа завершена');

Проверить(!г_лРаботаЗавершена);
м_Журнал.Вот(`[Запускалка] Начало работы ${performance.now().toFixed()}мс`);
```

Just found that this extension is causing me to be unable to watch Amazon Prime videos. Each video would show some message like "That shouldn't have happened." I tried a few troubleshooting steps but nothing helped. Disabling this addon made it so i can watch amazon stuff again.

Everything works flawlessly now. (as of jan 27, 2026) Only issue I have is that it auto-opens the player and doesn't revert with ?twitch5=0 when it notices that there's already one open. Oh, yeah, also pls add middle clicking support on the upper bar cuz it currently makes the UI disappear.

Can't receive twitch drops via extension. Fix pls, otherwise great extension.
