Firefox Community Forum

This has happened on two different video sites already. While watching a video, it will go extremely dark and happens randomly. I also get a weird blank window frame sporadically. I've unjustly been reporting this to one of the video sites until I noticed the same thing on Youtube.

I am unable to make or receive video calls in Facebook and WhatsApp. I used to be able to in Facebook. The message I get is that my browser doesn't support video calls. What is wrong?

Whenever I hold down the mouse button or space bar to speed up a video by 2x, it seems to let out a small crackle / pop, it wouldn't be as annoying if it only happened one time but it happens practically anytime I do it, sometimes it's when I first press it down, and sometimes it's when I let go.

I've been using Firefox for years and never had this issue until like 3-4 days ago I'd say, and it's a small thing but it adds up constantly and makes the experience fairly annoying, I tested the audio on google chrome extensively and it doesn't seem to happen there so I have to assume it's a Firefox issue.

Would love to see if there's a way to fix this.

Please help me as i want to record some gameplay but it keeps getting squished & it is pissing me off. I have asked on reddit & people were unhelpful & telling me to just buy another computer. this is annoying as it is causing me when playing games it causes text to be unreadable at times. Thanks in advance.

Good afternoon

recently i tried just realise my firefox can't played HEVC streaming video like twitch etc. (1st pictures)

i check on other browser such as Chrome, Edge, etc. it's played normal i check on google all about config

like media.wmf.hevc.enabled , media.hevc.enabled , dom.media.webcodecs.h265.enabled all set to true. checking on about:support i found it's not supported (2nd screenshot)

i check on Powershell are like this :

C:\WINDOWS\system32> Get-AppxPackage | Where-Object {$_.Name -like "*HEVC*"}

Name  : Microsoft.HEVCVideoExtension Publisher  : CN=Microsoft Corporation, O=Microsoft Corporation, L=Redmond, S=Washington, C=US Architecture  : X64 ResourceId  : Version  : 2.5.33.0 PackageFullName  : Microsoft.HEVCVideoExtension_2.5.33.0_x64__8wekyb3d8bbwe InstallLocation  : C:\Program Files\WindowsApps\Microsoft.HEVCVideoExtension_2.5.33.0_x64__8wekyb3d8bbwe IsFramework  : False PackageFamilyName : Microsoft.HEVCVideoExtension_8wekyb3d8bbwe PublisherId  : 8wekyb3d8bbwe IsResourcePackage : False IsBundle  : False IsDevelopmentMode : False NonRemovable  : False IsPartiallyStaged : False SignatureKind  : Store Status  : Ok Capabilities  : inProcessMediaExtension,

in summary it's installed and running.
