Hello community,

Since the last update, I have been experiencing issues with streaming services, such as Disney+. Playback is no longer scaled correctly in full-screen mode.

During playback, the image is displayed much smaller with black borders at the top and bottom, as if Disney+ and Firefox are unable to communicate the format correctly.

I have already searched the web for this issue and have not found any articles with the same error description.

System: Win11 Pro, everything is up to date, WIN resolution: 3440 x 1440 (125% scaling)

Attached is a screenshot with the playback in full screen mode. I have framed what is displayed.

Trying to run Prime and Netflix in a Linux browser on my new Lenovo Chromebook Plus 14. Not that this is an ARM based unit (Kompanio Ultra 910).

I can successfully download Firefox for Linux: Mozilla Firefox Debian Package mozilla-deb-1.0 144.0 (aarch64)

But when I go to run streaming video services get: Prime Video is incompatible with your current operating system or web browser. You must update to watch Prime Video titles. Review the Prime Video system requirements. If the problem continues, please contact Amazon Customer Service and refer to error 7132.

Same with Netflix.

any ideas, thoughts, solutions?  :)

Cheers.

Hello,

Youtube, BBC etc video files are not playing at all in the latest version of Firefox. I am on a Macbook Air OS 12.7.6.

I have tested the same pages on Safari and Opera browser and they are fine.

Please advise,

Regards,

Following a reboot yesterday I could not get any audio output from any web page. I checked my output speakers using windows and found no problem. I opened Edge and had no problem. I can play video recordings from other external sources with no problem. This is something within Firefox. I have tried the various investigations from the help system and none of these worked.

I need assistance resolving an issue where videos on YouTube play choppily in Firefox. The playback stutters frequently, even at lower resolutions, while other browsers stream smoothly. I’d appreciate guidance on troubleshooting steps to improve video performance—such as checking hardware acceleration, browser settings, or possible extensions causing the issue.

Hello! I'm having an issue specifically in Firefox Developer Edition only. Whenever I set a video to go fullscreen from any domain/service, little strips on the top of left of the fullscreen video show my desktop (shown in attached screenshot). I've tested this in regular Firefox as well as Google Chrome and fullscreen videos work just fine on both of those browsers.

Before this current version update, this problem would happen the first time putting a video in fullscreen, but every subsequent attempt during the same browser session would not have the issue. However, I'm now unable to achieve a true fullscreen video in Firefox Developer Edition no matter how many times I try.

Currently on version 145.0b3 (64-bit)

How to fully load a 1-hour long video directly? Now when watching videos, only a short section can be loaded, and it will stop loading after about 5 minutes. After watching the video, the subsequent content will continue to load. How to fully buffer a video in the background while pausing it?

!. 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.

I seem to get really high CPU and memory usage only when I run youtube on Firefox. This issue never happened before. How can I fix this?

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

Why am I not able to get sound when watching a video while connected to the internet? If I use Chrome or Edge the sound is fine. Could it be an incorrect setting? Or is this a common problem you are already aware of?
