I would like to be able to turn off preload of videos (and images) so that I can watch a page with a lot of videos and only load those that I want to see. This is important if you don't have a high bandwith or a lot of data. I am sure I have done this before but now I am not able to achieve that.

Thank you in advance, Virtually yours, David

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?

It was working fine until the day before yesterday. The volume of the speaker got low before it stopped working. The PodCast and Vimeo are working fine. So it is not the problem of my computer speaker.

When I'm on websites such as Reddit or Facebook, and I'm scrolling down, if I come across more than one post where there is a video, the screen will start to flicker. Only one video will play, but the screen flickers. If there is only one video on the screen, it is fine.

I can turn off Hardware Acceleration and this will resolve the issue, however, when I go to other sites such as Apple TV or GeoGuessr, the sites lag until I turn Hardware Acceleration back on.

The issue seems to be between Hardware Acceleration and when multiple videos are loading on a page.

Started OBS Vitrual Camera option. in Firefox the camera is no listed.

https://webrtc.github.io/samples/src/content/getusermedia/gum/

How can virtual cameras listed in Firefox?

``` $ v4l2-ctl --list-devices --all OBS Virtual Camera (platform:v4l2loopback-000):

       /dev/video0

SandbergCapture: SandbergCaptur (usb-0000:07:00.0-1):

       /dev/video1
       /dev/video2
       /dev/media0

```

but OBS Virtual Camera is not listed

When I play YouTube videos in Firefox for Android, the video keeps pausing and buffering constantly. I have tried clearing browser cache and disabling all extensions, but the problem still occurs. My device is Android mobile phone. I hope to get help to fix this playback stuttering issue.

usually when i click my keyboard's knob thing, it will pause and unpause whatever media is playing. but recently it's stopped doing that. it will work for anywhere between 2 mintues to 30 minutes, but eventually it stops. the only way to make it work again is to refresh the page or start a new page. the troubleshooting steps i've taken is: -close other media software (spotify, other tabs etc) -gone to abouy:config and typed in mediakey to check it works. also turned it off and on for good measure -turned off xbox gamebar -turned my pc off and on again. none of those worked i also thought it might be autoplay being turned off, but it didnt do anything. please help. thank you

Hello I am using Google Flow on my Linux PC and when going to edit scenes I get an error about a missing Codec. If I use Brave browser works fine so this makes me think this is not an OS issue but browser.

this exact question has been asked last year, none of the suggestions work: I am running Firefox 154.01 on Winux I have lost sound on Firefox. I have opened the same sites in Chromium and the sound is working fine. It's only in Firefox. I have tried several sites including , YouTube, and radio programs, no sound from Firefox. All of a sudden the sound disappeared. The speakers is turned on the volume is up, just not a sound from Firefox. What to do? Right now I had to switch over to Chromium

YouTube videos are frequently buffering and sometimes play slowly in Firefox, even when my internet connection seems to be working normally. Please help me identify the cause and suggest steps to fix the problem. I would also like to know whether any Firefox settings, extensions, cache, or hardware-acceleration settings could be causing this issue.

Hello Firefox support. I'm having trouble joining meetings in calling applications where I stream my screen from my laptop. I tried several different applications on my Windows 10, and unfortunately, in the Firefox browser, the audio doesn't work at all in various different applications, which reveals that the problem isn't the app. I couldn't find help in Mozilla support, so I'd like to know how I can stream my screen (either full screen or in browser, etc.) along with the audio so that everyone in the meeting can hear the sound of my computer. Thank you.

I'm on a Mac desktop, Mac Tahoe 26.6.2, using the latest version of Firefox, although this frequently happened in previous versions. Audio often disappears from videos and reels. When I refresh the page, nothing happens. To get sounds working again, I have to quit Firefox and restart, but by then I've lost the reels I was watching. This is a big issue for me as I am a musician. Any ideas on how to fix this permanently?

For the past month, out of the blue, I have been unable to play Spotify via my web browser. After troubleshooting with Spotify chat, it seems the issue is actually Firefox, because if I choose to play it via the app installed on my computer, it will play, but not via the web browser.

It was display "Spotify can't play this right now".. then it will skip through three songs, play ads & then will play the first 10 seconds of audio of the next song & then it will cut out.

Anyone else experiencing issues with Spotify via the Firebox web browser?

FF dev 155.0b5 (but this has been ongoing for 1+yr). W11p. Is there somewhere in settings where I can "disable" whatever is blocking videos from being seen? (for example BBC news videos). I have to go to troubleshoot mode to watch. I have previously disabled all potential blocking exts like ghostery & UBlock, but to no effect (still no videos). I have looked in security in settings. Otherwise, I either go to troubleshoot or open chrome. Or, is there an extension that will allow that video viewing? Please advise, thank you.

Hi. Every time I go into youtube, the sound cuts out after about an hour. I then have to go to settings, volume mixer and Mozilla Firefox and click on the X to get the sound back. Youtube has assured me this is not their problem, but a Mozilla one. I've been with Firefox for many many years and have never had this problem. Could you please advise me as to what to do about this ? Thank you.
