Speech output for Albanian on the website "loecsen.com" > language course "Albanian". Words cannot be heard under Windows 11. What can I do? I downloaded the Albanian language pack, but the voice isn't there. Is this a Firefox or Windows problem?

Greetings from Switzerland

Hello, I'm having a problem on Windows 10. It's a fresh windows installation and I tried already some solutions: reinstalling firefox, deleting cache, refreshing firefox, private windows, no add ons, trouble shoot mod. Nothing helped. The problem seems to be with live stream, either on twitch.tv or youtube.

Just updated to 144.0.2 (aarch64) on my MacMB Pro running Sequoia 15.7.1 with no other changes and now I can't play any YouTube videos, whether embedded in a website or YT directly. Get eithger a black screen or white, such as below. What arcane setting do I have to mess with now to get this back to normal? (OK in Safari.)

Hello Mozilla Support Team,

from yesterday playback speed on youtube is not working. When I open the same video with Edge playback speed is available.

Could you please check and rework?

Thanks in advance.

Many greetings Stefan

Dear, When playing a video on Youtube, Jellyfin or listening to the radio the video stops after a second of playing. Restarting FireFox works for a short amount of time and after that constant pausing of video's after pressing play. Really annoying.

What I allready tried - What is pressed --> none - Rebooting PC --> 5-10 min fix - Restarting FireFox --> 5-10 min fix - Updating FireFox --> Was on the newest version of 28 OKT 2025 - Updating Windows 11 --> Was on the newest version - Problem Solving Mode (So plugins/addons disabled) --> No fix - Chrome --> Works perfectly - Brave --> Works perfectly

Any idea's/fixes

Neither the [`

So how do I get them running? A significant portion of the internet runs on WebM and the fact that Mozilla's own dev docs can't show examples is a good indication of a problem.

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.

When I am watching a YouTube video and switch tabs, sometimes, on return to the YouTube tab, I have no sound. It is not muted. The system sound is fine. This does not always happen. I can switch tabs and still hear the sound. Then switch back and no sound. The video is not paused. I've tried pausing and playing the video, still no sound. Refreshing the tab doesn't help Where do I go to turn the sound back on? Win11, Firefox v144.02 64 bit.

I have a new Yoga Pro 7 and installed Ubuntu 24.04 on it. Cannot enable hw acceleration on it. Support page is given below. It says disabled by gfx. Also vainfo output is given below.

In Firefox, When H264 frames are decoded and rendered within a single tab, the output reaches up to 180 fps, performing well and meeting expectations. When decoding and rendering occur on two separate tabs on parallel, performance significantly drops, impacting both processes. However, it performs smoothly when running on a single tab.

In comparison to the Brave browser, H264 decoding and rendering are noticeably slower in Firefox. Firefox manages only around 180 fps, while Brave and other Chromium-based browsers can achieve approximately 1000 fps on a single tab and around 800 fps when multiple tabs are open.

Firefox is no longer playing audio from the Internet. I am running Firefox on Windows 11, and have the latest update installed (10/29/25). What happened? How do I fix this.

I am 99.5% sure this is a Firefox issue, as I have no problem playing audio files stored in my computer, and no problem playing Internet audio using Chrome or Edge.

Help!

I'm experiencing random (every few days) audio issues on 140.4.0esr on Debian trixie. Sound would randomly disapear. Firefox doesn't show on pavucontrol. Restaring pipewire doesn't help. To resolve I have to wipe FF profile and start from new profile. It is very annoying. What could be causing this problem?

Thank you.
