Firefox 社群討論區

I've freshly reinstalled Windows 11 and after trying to access and watch a movie on any of these sites I get an error (see the pictures).

Browser version: 137.0.1 (64 bit) Widevine version: 4.10.2891.0

Already tried to disable/enable DRM. Already reinstalled firefox. Already manually installed widevine. No clue what could be causing this issue.

"I’ve been having trouble with choppy YouTube videos in Firefox. It happens on both Wi-Fi and Ethernet connections. My system is running Windows 10, and I’ve already tried disabling hardware acceleration and clearing my browser cache. The issue persists even when I’m in Safe Mode. I’m using the latest version of Firefox (XX.XX). Any suggestions on how to fix this?"

So, my problem is with HW acceleration in FF. Basically:

If its enabled: It causes graphical artifacts in videos [See screenshot]. If its disabled: It brings screen tear in to videos and autoscroll [Like if Vsync is disabled in games].

I tried safe mode, I tried reinstall of FF, I tried disabling and enabling extensions. I tried to set Vsync on in Nvidia control panel... the only thing that impact those bugs is HW acceleration in FF.

My drivers are up to date, my browser is up to date, yet there is such trouble.

Any ideas or solutions?

Hi,

How can I force Nightly to play a media type ? Per instance, the top main video here : https://www.lapresse.ca/international/asie-et-oceanie/2025-12-23/coree-du-nord/kim-jong-un-inaugure-un-complexe-hotelier-dans-une-station-de-montagne.php

Best regards iBenny

I have Win 11 dell computer that does not play or pick up sound from web sites videos .I checked and tested my sound using the Microsoft platform & buy playing a disc. It works OK

I have HDR working in Proton games and mpv fine (using Plasma 6.4 / Wayland)

I enabled HDR in Firefox (gfx.wayland.hdr), and HDR content works in YouTube fine ( looks amazing!) however.. I have an issue in that all non HDR content doesn’t show any video (I have sound) just a green sceen (see screen shot) including all ads.

Any idea how to work round this ?

I have AMD 7800 GPU .

Cheers

!. 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.

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.

Trouble with streaming services(like youtube(only streams ), twitch, music streaming) on nightly Firefox Nightly 145.0a1 (2025-10-11) (x64) Cachy OS Binary from firefox.com

This is the link to the video that will not play in FireFox. https://www.swingtechnologies.com/UploadVideos/clarkj@pobox.com/S200629_019 B.mp4

For years I have been able to watch a foreign TV website, despite having only a DSL connection (I allow only the scripts essential to make it work). Since I did the last update, to 137.0, I cannot watch either the live stream ("General source error") or old programs ("There is something wrong with your internet connection"). This is absolutely consistent; I've lost count of the times I've tried.

I never had problems like this before. At worst, if Windows was running a background process I might have to stop it to keep from having pauses in the program. All I can think of is that you did something in the new version of Firefox that has made video impossible on DSL.

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.

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 ^_^.

Hello, I am currently using windows 11 with firefox 149.0. Regardless of what website I use (youtube. steam etc), the browser struggles to establish consistent connection to my bluetooth earbuds. It connects for one moment, but then soon the volume goes out and eventually it disconnects. Though it would reconnect soon, the cycle just keeps ongoing. I have experimented with other apps and browsers, as well as multiple bluetooth earbuds of other brands to be sure that it is a firefox issue. I have checked the volume mixer menu to ensure that there is nothing wrong. I have also made sure that my drivers are all up to date with no issue. But the issue still persists.

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?

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

I am running Firefox 144.0 on kubuntu 24.04.3 LTS I have lost sound on Firefox. I have opened the same sites in Chrome and the sound is working fine. It's only in Firefox. I have tried several sites including Udemy, YouTube, and radio programs, no sound from Firefox. The problem started in the middle of a Jit.Si session. All of a sudden the sound disappeared. I thought that restart Firefox would help, then restart the computer would help. But the problem has continued. The speakers is turned on the volume is up, just not a sound from Firefox. What to do?
