Firefox Community Forum

Hello! For some time now I suddenly have no sound in Firfox, otherwise the sound works everywhere, even in other browsers. All help instructions do not help. Do I have to switch to another browser for good? Thanks for help

No matter what settings I change, I still can't get audio to play from Firefox. I can use other browsers and get audio so I know it’s not my computer. I’ve even tried to uninstall firefox and install the newest version with no luck on getting my audio issue resolved. If anyone has any advice for me, it’d be greatly appreciated

Hi, for some time now I've been having problems with Mozilla Firefox, nothing is heard in YouTube, I reinstalled it but still the same problem, in Google Chrome the sound works, what can I do? And this is from the latest update.

Just built a new PC and using Win11. I like to have a pinned tab in Firefox playing some kind of media to have background noise. Since new build, whenever I am not 'focused' on that tab and doing other tasks, audio from that tab will cut/fade in and out.

I've been working on this for 16 hours. I've googled, binged, even yahooed. No answers. Checked and rechecked all settings, both system and browser. Uninstalled/Reinstalled *many* applications, including Firefox. My OCD won't let me rest till I have this solved.

Thanks for the help.

MP4 Not loading:

I have uploaded a few MP4 animated images to our website, but they are not loading in the Firefox browser. It looks like they are getting corrupted. This issue only occurs in Firefox. I’ve also attached screenshots for reference. Can someone help me understand why they are loading like this?

Hello everybody, i hope you are having a great day!. I have a problem with Youtube about the frames drops, in 1080p60fps i have drops but in 1080p normal don't. For system operative i'm using Fedora 43. And the Firefox version is the 145.0.1 64 bits. My specs are low: Intel i5 6200u with his integrated graphics (Intel HD 520) Already installed the extension h264ify, and i think i have all the correct drivers and codecs from the rpmfusion (ffmpeg, mesa freeworld) If u need more detail and information i can give it to you.

Bug in FireFox ... gives me a blank screen when trying to access this link : https://harrisonburg.org/music_scene/song_list/songs/Werwolves_studio.mp3

Has worked well for years, but with updates you broke it.

When playing YouTube videos in fullscreen mode, the video appears to skip as would be expected with frame drops. However, with stats for nerds open on the videos, no frame drops are reported and buffer health is fine (40+ seconds).

I'm on an up to date version of FireFox, I've tried with hardware acceleration both enabled and disabled, I've tried opening task manager to see if system usage looked weird (it doesn't, although it's not like I can have TM running while the video is playing in fullscreen so hard to tell) and am at a complete loss. All drivers for CPU and GPU are verifiably up to date (did full system check three days ago) and the only conclusion I've been able to come to is that it must be either a problem with FireFox or a problem with YouTube. I've seen no recent reports on any of the forums that I can find pointing to either as the culprit. So if anyone has any further ideas or solutions, I'd love to here them.

audio is not playing in firefox, nor does it appear in my third party sound mixer like it usually does. it does appear in windows' sound mixer, but does not play any audio. i have refreshed firefox and checked my drivers and my devices work fine. firefox is the only application on my computer that refuses to play audio.
