This is the link. I can't send animated images as the text is too small, so I'll describe it instead. It's so hard as a loyal fan, I'm crying.https://www.bilibili.com/bold text。There is a bug. Why does the Bilibili website not display the corresponding screen when I try to move to it? Speed playback cannot be used at all, and there’s also the issue of not being able to use fullscreen on Firefox. Are you forcing me to use another browser?

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.

FINALLY got my zorin os to update, and now also have the newest version of firefox uploaded and working. My singlefile addon works properly, I have upgraded to the newest versions of my video downloaders, and I have cleared my history, but my 2 video downloaders still don't recognize any videos on youtube. Any suggestions or alternative downloaders?

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

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.

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

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.

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?

Do you know of a mod that won't allow Youtube to have a resolution higher than 720p, including when embedded? I almost-always have Youtube at 480p when watching through their site. I noticed that when watching a video on another site and that it's embedding Youtube, that the resolution is higher > 480p and in those cases it's not rare to be > 720p.

I'd like a mod or setting so that when it's active that Youtube can't have a resolution higher than 720p, including when embedded. Any idea if there's something alike?

Thank you kindly for your help

Hello,

I recently updated my Firefox browser to the latest version, 138.0.1 (64-bit), on Windows.

After the update, I noticed that when playing videos in fullscreen mode (for example, on YouTube or other video websites), the Windows taskbar (the bar at the bottom of the screen with the Start menu icon) does not hide automatically. This is affecting my fullscreen viewing experience.

Before updating to version 138.0.1, the Windows taskbar would hide correctly when entering fullscreen video.

I was wondering if anyone else has encountered a similar issue with the Windows taskbar not hiding, or if there are any suggested solutions to help resolve this problem.

Thank you for your help!

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?

This is a functional bug, not a settings issue. Block media autoplay in Firefox cannot work, after I right-click on a blank area of the page and scroll.

For example, I saw a post with a video on x.com, and the site was set to prohibit automatic video playback. But when I right-clicked on the webpage and then scrolled the page with the mouse, the video started to play automatically, which means that the function of prohibiting video playback was invalid. Very strange.

Firefox version: 141.0.3 (private-browsing No extensions are running) OS: Windows11 Enterprise 26100.4946

Hello, I did a lot of search and followed all these advises: https://support.mozilla.org/en-US/questions/1229615 https://winaero.com/remove-your-browser-is-being-managed-by-your-organization-from-firefox/

1. I have not entry "DisableFirefoxAccounts" in "HKEY_CURRENT_USER\Software\Policies\Mozilla\Firefox". 2. I have no policies.json file in firefox directory. 3. I have a message "Your browser is being managed by your organization." in "Settings" (about:preferences). 4. In "about:policies" I have DisableFirefoxAccounts=TRUE. 5. in "about:config" identity.fxaccounts.enabled=false and grayed out.

Please help me to turn on the sync of bookmarks. All these listed issues obviously have something to do with it.

Since I updated to Firefox 141.02 I have not been able to play videos on Paramount+ or Netflix. I get an error on the top that says the Widevine plugin has crashed on both streaming services. I have checked that the plugin is on and there are no updates. I am on Ubuntu 24.04. Video on YouTube plays as normal

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.

Hello,

NVIDIA RTX Video Enhancements are not working in firefox at all. By not working, i mean neither Super Resolution neither HDR enhancements work at all, not even the badge shows up, and the NVIDIA app reports the status as "inactive". The video is not upscaled, and the content isn't getting put into HDR. It is on globally on my system, and does work on all the chromium based browsers installed on my system, even on the discord app itself.

I tried a latest firefox fresh install, with youtube playback, or just opening a video file directly with the browser. This worked on chromium browsers, but not on firefox.

I'm on windows 10 64bit with a 3060 gpu. (the only gpu in the system.) I have 4 monitors connected, but still get the same issue with only one. Hardware decoding is force enabled, and about:support reports that hardware decoding is supported for H264, VP8, VP9 and AV1 too. I even get the same amount of video-decode usage in task manager on both chromium and firefox while video is playing.

Thanks in advance.

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

Issue Description: I’m experiencing a problem with fullscreen mode while using YouTube on Firefox on Windows 11 with a dual-monitor setup. When I enter fullscreen, the video does not cover the entire screen. Instead, I can still see parts of the Windows desktop or background around the edges of the display.

This issue only happens on Firefox and only when using fullscreen mode on one of my monitors. I have already checked my display settings, scaling, alignment, and hardware acceleration, but the problem persists.

System Details:

Windows 11

Dual-monitor setup

Browser: Firefox (latest version)

Issue: Fullscreen video shows borders and does not fully cover the screen

Expected Behavior: The fullscreen video should completely fill the selected monitor without showing any part of the Windows desktop.

Please advise on how to resolve this issue.
