Firefox completely crushes my webcam when using Google Meet - Windows 11

Sajidul Hasan

Hi There,

I'm a Professional Web Designer, and I need to make a lot of meeting through Google Meet. I was using Chrome previously. When I try to use my Web Cam, Firefox completely crush my web cam. Means, no other apps can't use the web cam including Meet until I pull the flag out of my PC's USB port.

The only fix is to disable hardware acceleration. But I need that as well. So chating Gemini, I figured out that changing this rule media.windows-media-foundation.allow-d3d11-dxva to false on about:config fixes the issue with having Hardware Acceleration enabled.

It turns out that, according to some reddit uses, Firefox uses API from medieval age for handling DirectX3d.

I love Firefox, and I want it to grow nowadays more than ever by looking at the browser market and what they are doing with Ad Blockers. Please take a look at Firefox's performance for the good.

My System: OS: Windows 11 Pro CPU: Intel Core Ultra 7 270k Plus GPU: NVIDIA 5070 TI 16GB No shortage of SSD and Ram. Plenty of them available.

Can Firefox work on that issue, so I don't have to go to workaround like this? I love Firefox and I want it to compete with chromium for good. But having issues like this left us no option but to choose alternative.

Thank you!

It turns out, I need to use these settings to get my Logitech webcam to work as expected on Firefox. Works on other browsers well.

media.windows-media-foundation.allow-d3d11-dxva → Set to false

media.hardware-video-decoding.enabled → Set to false

"general.useragent.override.meet.google.com" → Set to String "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.0.0 Safari/537.36"

It turns out that I have to use these flags to get my webcam to work properly.

"media.windows-media-foundation.allow-d3d11-dxva" → Set to false

"media.hardware-video-decoding.enabled" → Set to false

"general.useragent.override.meet.google.com" → Set to String "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.0.0 Safari/537.36"

NOTE: I've submitted the comment once and saw wasn't posted so, here I post it again. Thank you!

The combination of factors look more like a compatibility issue including both media and render with extra sprinkle of Meet sniffing on top — you might want to file this in bugzilla right away with the details to reproduce.
