Issue: “Encrypted broadcast” error on specific stream

Browser: Firefox 148 on Linux

Description:
The Alternate Player shows the message:

“This broadcast is encrypted. The extension does not support encrypted broadcasts.”

The stream plays normally in the official Twitch player.

This only occurs with one specific streamer; other streams work normally in the extension.

During testing, network capture showed the HLS playlist loading successfully from Twitch’s playlist CDN, with normal refresh intervals and segment delivery. This suggests the manifest is being served correctly and the issue may be related to an encrypted or DRM-enabled stream variant that the extension does not currently support.

If needed, I can provide HAR logs or additional network details.

Please add a darkmode for the chat :)

I need full-featuread dark mode

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

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.
