html5 video not displaying

Trying to set up HTML5 peer-peer video conferencing. Its working on Chrome but not Firefox. I have looked at all the available solutions. I have reinstalled firefox; I have checked that is set to "true"; I have checked in "safe mode".

This challenge is an issue which occurs 90% of the time. I have yet to assess what conditions occur when html5 video is finally displayed. I can only say that display only occurrred once today and that was when I first inspected the site this morning.

This situation is occurring both in Firefox and the developer edition. Firefox is latest edition and there are no plugins

Any suggestions?

Based in UK. Can you direct me to a UK number please?

Number provided came up twice as no answer and then invalid. I am now also being asked to pay to contact.

Is there a UK number to call please; ....or a time when I will be able to connect with someone?

Thanks :-)

Plenty of chat options out there, but I specifically wish to have this issue resolved for Firefox browsers.

I'm not really sure, how to reproduce this issue. How do you try to run the video connection?

This is one of the pages I've looked at. It explains a very similar issue I am facing, but there is no solution...

I have checked my extensions; I have none.

My camera light is on and permissions have been granted for the site I am using.

It works on chrome and my mobile.

I have selected about:config and requested a list according to: media*enable; nothing is bold

I'm looking for a solution that goes beyond standard tests that I can find online, that generally list what I've tried above.

Firefox v74.0 (64bit)

The phone number you saw or received earlier is a scam. Please do not attempt to call that number.

Did you check the Web Console ?

Loaded the following URL:

From what I can see from the web console I see the following related to the "webcam test":

1. Cannot play media. No decoders for requested formats: text/html

2. The script from “…est%2F,” was loaded even though its MIME type (“text/html”) is not a valid JavaScript MIME type.

3. Source map error: Error: NetworkError when attempting to fetch resource. Resource URL: Source Map URL:

4. The script from “…0Gecko%2F20100101%20Firefox%2F75.0&dt=8736481428691810142000” was loaded even though its MIME type (“”) is not a valid JavaScript MIME type.

5. The script from “…est%2F,” was loaded even though its MIME type (“text/html”) is not a valid JavaScript MIME type.

I have also clicked the network tab, but no clues.

It works. You didn't provide the camera permission for that website. You need also the Autoplay video permission.

See How to manage your camera and microphone permissions with Firefox.

It doesn't on my Firefox browser. It has permission but there is no option for autoplay.

For the other site I am testing on, autoplay is turned on

What I mean is that you don't explain precisely what happens. What does happen with the video view of the other person ? Is this grey ? black ? Is there a question asked ? an error message ?
