What error did you see when you try to play the video?

On Firefox Release 130, the video played well for me. But on Nightly 133, I see Streams API / Invalid Platform. For Nightly error, I captured a profile and none of the media resource was loaded. So this doesn't seem like a media issue.

Hi Alastor. I get the same result as you now, but that was the error message I saw on Release as well.

Tested with:

Browser / Version: Firefox Release 131.0 (64-bit)/ Firefox Nightly 133.0a1 (2024-10-01) (64-bit)
Operating System: Windows 10 PRO x64

I'm going to guess this is hls related.

Caused by broken UA sniffing:

        // Firefox 1.0+
        var isFirefox = typeof InstallTrigger !== 'undefined';

this returns false, so the website thinks this isn't Firefox, and the platform is unknown, and subsequently an API call returns the error: Streams API / Invalid Platform. When doing:

window.Installtrigger = {};

right after load, things work as expected.
