Firefox Community Forum

So I'm having a small issue with the volume slider on youtube. The gray bar that indicates volume is about 1% of the size it should be (Please see attached image). It functions fine but bothers me enough that I've contacted support. I've opened it in safe/troubleshooting mode and the issue persists, and there in no issue on chrome. Any help would be appreciated, thanks ^_^.

Lost my audio on Firefox. All movies and web site videos SILENT

Strange exceptions: e.g., can't ear video on youtube.com; BUT, CAN hear it if web page has LINK to YouTube!?!? SOME Twitter videous have audio; others are silent

How do I turn Firefox audio back ON?

Media resource could not be decoded, error: Error Code: NS_ERROR_DOM_MEDIA_DECODE_ERR (0x806e0004) Details: virtual mozilla::MediaResult mozilla::FFmpegVideoDecoder<62>::DoDecode(mozilla::MediaRawData*, uint8_t*, int, bool*, mozilla::MediaDataDecoder::DecodedData&): avcodec_send_packet error: Unknown error occurred

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.

No audio on Firefox. Google Chrome has sound. Settings at normal audio volumes. Tried computer shut off and re-boot. Tried reload of Firebox.but that didn't help. Had scam attempt just before no audio issue...not sure if that problem.

hi for some reason twitch.tv or some other websites will no longer play videos on my pc and i have no idea why, firefox works fine on my laptop

I'm running the latest version of Firefox on the latest version of Windows 11, and I'm trying to watch TV shows on PBS's Passport service. I get the video but not the sound. It's been like this since Saturday. I don't have this problem at all with Chrome or Edge. Is anyone else having this problem? JT

Make amazon product video work on firefox. I am using fedora 43 kde plasma recently updated. I have a Nvidia video card RTX 5060 ti and using propriety Nvidia drivers Video starts and then stops or after turning off hardware accelaration ran intermitantly then stops. Sometimes telling me the video file is corrupted

Hello! My firefox get a problem: The taskbar does not disappear when switching the video player to full-screen mode (the attached screenshot shows what it looks like). Clicking the browser icon on the taskbar a few times makes the taskbar disappear, but the problem recurs the next time full-screen mode is entered. This happens in all video players. Any solution to fix that?

I've seen many questions about this matter over the years, and thought I'd been lucky. Every link containing a .m3u file opened in my media player, WACUP. However ... after an update to version 143 it suddenly didn't. .m3u links opened as a text file in the browser window.

We have five windows 10 workstations in the home, and this happened with all of them.

I write webpages for a family intranet, and several thousand tracks are available for playing, so that was messed up too.

These are the steps I followed - unsuccessfully:

• Bulleted list item Checked file association settings in Windows 10. .m3u was associated to WACUP, my media player.
• Bulleted list item Checked file actions in Firefox. .m3u files set to open in WACUP.
• Bulleted list item Added the type="audio/mpgurl" in the anchor link for webpages I make.
• Bulleted list item Changed the default download panel in FF settings to "Ask". I could then get it to ask me to save or open. "Open" worked, as it this is tied to the system default audio player - nothing to do with FF.
• Bulleted list item A few other frustrating, but eventually inconsequential solutions that were in the realm of "I wonder if ...?"

So ... after all of this and a lot of investigation I noticed something interesting: All my playlists were in the format with just a listing of the filename, which as mentioned had been working for years:

Example "01 Queen - We Are The Champions.mp3".

Yet a playlist made in VLC had a different format: example,

"#EXTM3U

1. EXTINF:-1,01 The Beach Boys - Help Me Rhonda.mp3

01 The Beach Boys - Help Me Rhonda.mp3 "

SOLUTION

Having far too much time on my hands, I experimented with this, dissecting the various components of the playlist, and eventually found when adding "#EXTM3U" as the first line in the playlist, Firefox opened the playlist in WACUP once again when the link was clicked.

New playlist entry:

1. EXTM3U

01 Queen - We Are The Champions.mp3 02 ... 03 ... etc.

I've left the "type='audio/mpegurl" declaration in the link.

I don't know why this happened, but I hope somebody finds this useful in the future.

So now I have several thousand playlists to edit, although Notepad++ will make this easier, but by no means quick.

Okay posted this into iOS but never got any proper help, so I'm guessing that was the wrong place to put this.

Whilst I'm watching a video, if said video is playing in fullscreen, it'll often fade to black during different parts, as whenever a flash happens or quick cuts (e.g. a film with lightning strikes, causes it to fade to black and it stays like that - then fades back in super slowly). It is SUPER annoying and it causes me to have to rewind if I miss something because of it (only for it to do it again and again)! I don't watch YouTube in fullscreen because of it, but it even does it in streaming services - but worse! I honestly have had enough of this, it is genuinely infuriating.

I'm on MAC air 2022 M2, macOs Tahoe 26.6.2 - and the most recent up-to-date Firefox update: Version 157.0 I usually put off updating Firefox because it signs me out of everything! Meaning I have to resign into all of my school things, streaming, YouTube, and even this page itself!

Now I've gone into a private window and tested it to see if it does the same thing - yes, yes it does do the same thing, I put on the same two YouTube videos and it did the exact same fading in the middle of it at the same exact timestamp!

Took this photo of the movie Cruella because I knew there was loads of flashing lights at one scene. You can see that the video is faded but the rest isn't. The second image is when I click multiple times to try and stop it! But it happens again directly after.

Please help me, this is really annoying and I've put up with it for too long :(
