Firefox Community Forum

My sound does not work when using Firefox. But when I switch to the troubleshooting mode in the "Help" menu, the sound works normally. I did not make any changes to sound settings. Sound was fine last night and did not work when I woke the computer up this morning. I am using Windows 11. Going from troubleshooting mode back to normal mode causes the sound to stop working again.

Tell me why I have no sound on Firefox and how to fix it. I do have sound on DuckDuckGo and AVG Secure Browser. I have checked my sound setting 55% and not muted. I have shut down and started laptop, still no sound. I checked Firefox updates and am good.

Today my Facebook has no sound. My laptop has sound. Youtube has sound, NBC has sound, Amazon Music has sound, NPR has sound, it's just Facebook that is WITHOUT SOUND. So that is why I am wondering, does Firefox/Mozilla have sound settings that I might access to fix something like this?

I have already tried rebooting the laptop. Rebooting the browser. Rebooting Facebook. Thank you in advance for whatever help you might offer, Pamela

The sound works for me on Opera (PC Win11), but not on Mozilla - I see it as a bug in the browser... even after clicking on the playback device in the bottom right corner in Mozilla, the sound doesn't start playing...

when I hit full screen in the lower left on youtube videos it says full screen unavailable on all videos. I have tried all the recommended setting adjustments in the config and they don't work. yet full screen for youtube videos works in all other browsers on my mac which is an M2 pro macbook pro running sequioa 15.7.4

Please fix this as it is really annoying and I may stop using this browser if it is not taken care of. It just started yesteday out of nowhere. No changes were made on my computer during this time.

Browsing this website article I can see that there are embedded Youtube videos in the article but they are not loading, instead I only see blank spaces. I've turned off all extensions, turned off tracking protection, cleared cache and cookies for both the website and Youtube.com, and tried viewing the website in troubleshoot mode.

I'm trying to stream a show in the firefox browser and I am getting error saying the HLS is not up to date. I've checked my firefox is at the latest update, is this something you need to update on your end?

господа,здравствуйте,помогите пожалуйста,любое видео разворачиваю на полный экран на мониторе HDR,а оно тусклое,никак не могу победить эту проблему,я бы отказался от всех остальные браузеров,но вот это единственное что меня останавливает

I have been looking for any "cast to device" button or setting on and off for a few weeks now and can't seem to find it. Not sure if it's just right out disabled in the browser (because other sites allow me to cast), but YouTube specifically just doesn't have the option anymore. Just wondering if it's something on my end or if it's fixable at all.
