Marking as P1 during triage discussion. Can we try to figure out when this regression started?

I tried testing with that site on my device and keep getting 404 errors with that site.

We know that it works in beta 7 and that it no longer works in beta 9.
here are the patches between these 2 versions
https://hg.mozilla.org/releases/mozilla-beta/pushloghtml?fromchange=FIREFOX_67_0b7_RELEASE&tochange=FIREFOX_67_0b9_RELEASE

Mirabela, could you test again with beta 8 so as that we can reduce the regression range please? Thanks

Hi Pascal,

I couldn't reproduce the issue on Firefox Beta 67.0b8 on Desktop, but I have to mention that I couldn't reproduce this issue with 67.09 neither on Desktop. I could only reproduce on Firefox for Android Beta 67.0b9.

Thank you!

I think bug 1539220 might be a candidate for causing problems.

Can you check if this one patch from bug 1539220 is causing the problem on Android?

If not could you get us a regression rage on Android?

The changes from Bug 1539220 are only used when accessing the camera through getUserMedia. That does not seem to be the case with this page.

Hi,

I cannot find a regression range, because this issue only happens on Beta 67.0b9 on Android. It isn't reproducible on Nightly, RC, or Beta 67.0b7.

Thanks,

Testing on my devices, a Huawei P10 and a Nexus 6P, Beta 67.0b9 works fine for that site.

Have you tried running mozregession for the affected device? The following command should use Beta builds, although when I tried it, it definitely skipped some revisions because no builds were available.

mozregression --app fennec --repo mozilla-beta -g 157a891a7630 -b b6fdd2540f52

It is not reproducible on Beta 67.0b11, with Huawei MediaPad Mi2 (Android 5.1.1), so I will close this issue as Worksforme.
Thank you!
