When watching videos, switching between my Bluetooth headphones and Mac speakers will cause the sound not being able to output correctly, the video will be seem muted. Sound output is fine when using other explorer and apps. Restarting Firefox will usually fix the problem.

i can't watch a streaming movie without it stopping to buffer through out the whole movie . I never have a problem watch TV shows. It wont upload the stream long enough to keep playing . Can i increase the streaming a head so the movie doesn't stop playing till the end.

No sound when showing videos, i.g youtube etc, in firefox. Works fine in Chrome, and yes, the volume is on in firefox and laptop (Win11).

Is there a setting I have inadvertently touched.....?

Thanks!

This problem started yesterday. The sound in YouTube with Firefox is extremely low. As far as I can tell, the problem doesn't exist elsewhere. Other browers are OK with YouTube and other websites that have sound are OK with Firefox.

I reinstalled Firefox and rebooted the computer - still has the problem.

I'm using Windows 11 24H2 (home) on my desktop.

This issue came up in early April 2025.

Programs other than Firefox (e.g. Edge, Media Player) behave normally: when playing sound, if nothing is plugged into the 3.5 mm jack, the sound comes from the desktop's external speakers; and when an audio device (speakers or headphones) is plugged into the 3.5 mm jack, the sound instead comes from that device.

Where as Firefox will play using the internal speakers as expected, but when a device is plugged into the 3.5 mm jack, no sound signal goes to that device.

It seems then that the hardware is okay, and the problem must lie within Firefox, or within a Windows setting that is very specific to Firefox.

The sudden onset earlier this month may point to either a Firefox update, or (less likely) a Windows update.

Hi. There is a problem with video playback when skipping through the video using a playback bar. The video (but not audio) freezes at the spot when one skippes to another part of the video and re-establishes after a while (not so short while) to the part of the video that is currently played. I'm using Linux Fedora.

Initially connects video playing to Headphones via Bluetooth then audio stops. Reloading doesn't help. But the same works perfectly on other browsers. Problem is with Firefox audio setting. The problem started only a week ago for firefox

Since the last update, I believe, because this error occurs constantly and with EVERY video. This is often, not always, the case immediately after updating FF. Now it was fine for a while, but now it's so bad that I'm having trouble watching YT videos properly. Reason: Browser open, logged in to YT. I click on a video to play - video opens, plays maybe 10 to 20 seconds, then playback stops spinning top, I also found out during the last glitch after update that if I switch the resolution briefly, higher or lower doesn't matter - important is to leave the current resolution and switch to another one. And oh wonder - immediately, instantly with the change, the video starts playing. If I wait for this - without doing anything myself, it sometimes takes 30 - 40 seconds for the video to start ... sometimes it just "hangs" ... This is extremely annoying - if it doesn't work, I have to switch browsers... What is also extremely annoying is that it occurs almost regularly after an update ... until the next one possibly, for unknown reasons, does not fix the error, but sometimes mitigates it. Now, however, the disruption/interruption is so massive and totally annoying that I'm thinking of switching. I'm just tired of it ...

When watching a movie, the video blacks out and this message appears, is there a fix for this issue? "You aborted the media playback" appears about every 6 minutes, refreshing doesn't fix the problem

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?
