I was able to reproduce on this pages as well:

- https://codepen.io/kus/pen/aOqvWP/

Marking the bug as NEW. Tested with HTC 10(Android 8.0.0).

Note that https://bugzilla.mozilla.org/show_bug.cgi?id=1486659 is marked as fixed, but the bug, as reproduced in https://bugzilla.mozilla.org/show_bug.cgi?id=1481406#c2, is still present in Firefox for Android v68.2.1.

Yes, I confirm that. This bug has been around for a while now and is not fixed on latest Firefox for Android.

I can also replicate this on Firefox for Android v68.3.0 using the codepen link provided (https://codepen.io/kus/pen/aOqvWP/). The canvases are empty despite videos having loaded, and an error message "NS_ERROR_NOT_AVAILABLE: " is logged in the console.

Works fine on Chrome for Android v79.0.3945.79 (both videos and canvases are rendered).

Should I file a new report or should this one be reopened?

Neither. Firefox for Android 68 is a finished product. Checking the behavior on Firefox Review and/or reference browser would be the thing to do they are using Gecko 73. https://play.google.com/store/apps/details?id=org.mozilla.fenix.nightly & https://play.google.com/store/apps/details?id=org.mozilla.reference.browser

If it reproduces on those builds opening a bug at https://bugzilla.mozilla.org/enter_bug.cgi?product=GeckoView would be useful.
