There seems to be a CSP error when loading the video, which might be related.

The channel is getting cancelled in HttpChannelChild::DoOnStartRequest here

The content type is application/vnd.apple.mpegurl and Firefox doesn't know how to display it, or the listener just returns 80004004 - NS_ERROR_ABORT from OnStartRequest

Already answered in bug 1919592.

The bug for this was moved over to dom workers. No longer a media bug.

Comment 5

[Jeff Muizelaar [:jrmuizel]]

I'll confirm the current state.

Comment 6

[Jeff Muizelaar [:jrmuizel]]

This doesn't work for me in Nightly or Release (presumably where HLS has been turned back on)

@asuth has pinged Google and Apple in https://github.com/web-platform-tests/wpt/issues/41745#issuecomment-2377512723 to see if they'll fix their implementations to match the spec.

Andrew, I presume any resolution to this from an update to Chrome/Safari will be quite some time in the future. Are there any possible interventions we could ship that would fix this at our end?

Otherwise, we'll need to reach out to Apple to fix their page.

Moving this to needs-contact, since even if Chrome and Safari were to land patches today to fix it, the site (Apple) would need to be updated.

We're in a weird state where it doesn't seem like either Blink or Webkit are planning to ever conform to the spec, but :annevk of Webkit doesn't want to change the spec. Eden is working on a mitigation/fix in bug 1471805.

It seems like maybe Apple fixed this? The initial STR lists a video that is no longer on their support site, but if I go to https://support.apple.com/en-us/118430?iphone-authentication-type=iphone-with-face-id which does have a video or https://support.apple.com/en-us/108366, I'm able to watch the videos on both Firefox Nightly Desktop on Linux and Firefox Nightly Android.

Reporter, can you confirm if the issue is fixed for you? Thanks!

I'm not able to reproduce the issue on both latest Release and Nightly on Android, works on both links.

Note: Not a Firefox bug but there's an issue when trying to close the video with "X", it enters in some kind of fullscreen mode and the page is unresponsive until you hit back. The issue reproduces on Chrome as well.

Thanks for confirming! Resolving WFM.
