On the topic of resource loading issues, another security fix in version 68 stops access to cameras and microphones in non-secure contexts
such as http, and, presumably, file://.
However, it looks like “cameras and microphones” also includes “other media devices”, as described at this link (scroll to the DOM APIs
section):
https://hacks.mozilla.org/2019/07/firefox-68-bigints-contrast-checks-and-the-quantumbar/
And “other media devices” apparently includes video playback.
We are now seeing an issue playing instructional videos (mp4) from an tag. When accessing from both file:// and from http://,
we get a blank page, with no content, and no errors in the console. When accessing from https://, the video plays.
I have tried giving the site permissions to access media devices, with no success. Even if I can get http working, I assume file:// would
still be broken.
Have I diagnosed this properly, i.e. is this video issue related to the “cameras, microphones, and other media devices” as described
by Dan Callahan in the link above?
Thanks,
John
