The partial code is :


< video onclick='playPause()' width='100%' controls > 

 < source src='/videos/".$trimDir."/".basename($s)."' type='video/mp4' >

</video>

The partial code is : &lt; video onclick='playPause()' width='100%' controls &gt; &lt; source src='/videos/".$trimDir."/".basename($s)."' type='video/mp4' &gt; &lt;/video>

I have a php file with an html video tag which recently stopped working in Foxfire Developer Edition (FDE). It still works in other browsers. In FDE, the volume is permanently muted. I can't find a way to turn the mute off. In About:Config and under Media: there are messages at: media.decoder-doctor.new-issue-endpoint = https://webcompat.com/issues/new and media.decoder-doctor.notifications-allowed = MediaWMFNeeded,MediaWidevineNoWMF,MediaCannotInitializePulseAudio,MediaCannotPlayNoDecoders,MediaUnsupportedLibavcodec,MediaPlatformDecoderNotFound The partial code is : < video onclick='playPause()' width='100%' controls > < source src='/videos/".$trimDir."/".basename($s)."' type='video/mp4' > </video>

I tried to reproduce the issue with sample video from https://samplelib.com/sample-mp4.html on FDE but it works

perhaps it is the video content, can you try to use other video files to validate the "mute" issue ?

I have tried other video files and the result is the same. Firefox Developer Edition won't unmute. I is within the FDE app, the volume symbol changes to the volume symbol with a line through it when the video starts.
