[Mozilla Enterprise] Help ! An annoying behavior seems to prevent audio/video working properly on Firefox 78 ESR behind a firefox, over a proxy with services using WebRTC such as Jitsi Meet

[Espitallier Laurent]

Hello,

an annoying behavior seems to prevent audio/video  working properly on Firefox ESR 78 behind a firefox, over a proxy with services using WebRTC such as Jitsi Meet.

No problem with Firefox ESR 68 or latest releases of Firefox.

Operating system : Windows 10 1909, 20H2

We really need it to work...

Do I need to fill a bug or is there something else to do ?

Thanks.
