Firefox Community Forum

YouTube videos encoded at 60 frames per second are extremely choppy in Firefox only. Microsoft Edge plays the same videos perfectly.

I have deleted my profile and reinstalled Firefox, updated graphics driver to the latest version, and toggled hardware acceleration on and off. Nothing helps.

I am using FF desktop. All of a sudden, I get no sound through my laptop speakers when trying to watch videos (on YT and FB for example). I still get sound if I use external speakers through the 3.5" jack. I still get sound through other browsers, no matter if it's through the laptop speakers or external ones. So, it is definitely an FF problem. Sound works fine on all other media files on the laptop. Refreshing FF didn't fix it. Nor did reinstalling or restarting the laptop. I tried changing the autoplay settings as suggested in the help article, but still no laptop audio via FF. How can I fix this? Thanks

After updating firefox from 128.8.0 to 128.9.0, no embedded videos will play (youtube, instagram, plex, etc...)

The only way to get them to play is to run the browser in troubleshoot mode. Even a fresh browser profile doesn't work. Disabling hardware acceleration also does not work. Tried firefox 137.0.2 and that also does not work. Downgraded back to 128.8.0 and videos play flawlessly again.

I'm running firefox on gentoo linux on a thinkpad x13s (arm64) which uses Qualcomm Adreno 690 graphics.

Anything I should try would be greatly appreciated. Thanks.

!. link to youtube only flashes then plays only audio. Full video requires opening link in a new private browser window

2. Typing into search bar for Duck Duck Go in new tab page types directly into active bar...

3. Active bar is no longer at the top but is in Bookmarks toolbar...

I suspect some update problem.

Whenever I play something in the browser while connected to my TV by HDMI, the sound still comes out of the laptop speakers. This happened suddenly, without any discernible reason, and I can't seem to fix it. Everything else works, only content played from Firefox remains in the laptop speakers. I've checked my audio mixer, nothing seems amiss, I've updated Firefox and refreshed the application, still nothing. Hell, I've even tried different cables and HDMI ports, but nothing works. What could be the issue? Why did my audio suddenly stop working, and what can I do about it?

Please 🙏 I am tired of the same thing nothing changes I will get control over my podcast and Cash app pay pal and they take it right back I truly know who's doing this where do I start

I've noticed that whenever I press ⌥⇧Space (option-shift-spacebar) in Firefox Developer Edition, it causes the page to refresh.

This behaviour seems to be consistent across devices.

Is there a way to change/disable this behaviour? It is very inconvenient, as it often causes me to accidentally trigger a page refresh when I type an em dash (`—`) in a text input (opt-shift-dash, and then type a space character after it, I'm very likely to hit opt-shift-space by mistake 🙈).

Since to your "upgrade"to firefocx on my computer I can no longer watch youtube or iplayer videos. Pease say how I can downgrade my version so as to be able to see these.

When I load the video the page loads like normal, all comments and everything is there except the video square is not there. cant see the video, anyhow. even if i move my mouse cursor on it on the start page, the little video wont play the preview. no video player at all. anywhere.

[redacted] problem you [redacted] im having issues with the video and ads as all of my apps are disabeld nothing works and firefox it self causing probs and no one is helping out.

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.

Good evening Mozilla,

Well I am facing an issue, no sound coming from any website like netflix or youtube or prime from mozilla browser.

Could you please fix it for me.

频繁使用视频快进/后退，会导致Windows 音频设备图形隔离（audiodg.exe）内存泄露，

复现： 浏览任意视频，使用方向键左右频繁切换快进/后退， 可以看到内存逐步增加，退出浏览无法得到完全释放， 若长时间使用最终会导致内存泄露，如播放列表频繁使用快进/后退 // 已尝试更新相关驱动，关闭部分音频相关功能，无法得到解决，目前推测是firefox问题， 使用microsoft edge尝试复现，无此问题
