Firefox Community Forum

This has happened on two different video sites already. While watching a video, it will go extremely dark and happens randomly. I also get a weird blank window frame sporadically. I've unjustly been reporting this to one of the video sites until I noticed the same thing on Youtube.

I am running 155.0.1 latest version at the time of this writing. I am able to log into Netflix, but cannot play content. Part of their trouble shooting was to disable and re-enable DRM (widevine). The problem is that now that I have done so, I cannot get widevine installed again. Is there a manual way to get this installed, clean up what Netflix was so gallant about messing up on my computer? I have seen some old and sketchy posts on redit and other places that suggest ways to do this, but they scare me. I searched the forums here, and didn't see anything that directly affected my question, although I might have missed it.

Thanks all for the help.

Hello,

I am experiencing a serious display flickering/refresh issue in Firefox when opening DRM streaming websites such as Netflix, Amazon Prime Video and HBO/Max.

My system:

GPU: NVIDIA GeForce RTX 3080 Monitor: LG 34GL750 Windows PC Latest NVIDIA driver installed

The problem:

When I open Netflix/Prime Video/HBO/Max in Firefox, the display repeatedly flickers or appears to restart. There is no "No Signal" message from the monitor. Closing Firefox sometimes makes the display recover. Unplugging/reconnecting the display cable has sometimes been necessary. The same problem does NOT occur in Brave, using the same PC, GPU, monitor and cable.

Troubleshooting already performed:

Updated to the latest NVIDIA driver, including the recent driver update that mentioned display-related issues. Tried a different display cable. Disabled Firefox hardware acceleration. Tested with Firefox Troubleshooting Mode — the problem still occurs. Disabled/enabled Firefox DRM/Widevine — the problem still occurs. Tested with a completely new Firefox profile — the problem still occurs. Disabled G-SYNC — the problem still occurs. Disabled uBlock — the problem still occurs. Checked about — there are no recent crash reports related to the problem.

Firefox about information:

GPU #1: NVIDIA GeForce RTX 3080 Active: Yes

In my normal Firefox profile: Compositing: WebRender (Software) HARDWARE_VIDEO_DECODING: runtime: unavailable Requires texture sharing Blocklisted; failure code FEATURE_FAILURE_BROKEN_TEXTURE_SHARING

In a completely new Firefox profile: HARDWARE_VIDEO_DECODING: default: available

However, the display problem still occurs in the new profile.

Thank you.

When I'm on websites such as Reddit or Facebook, and I'm scrolling down, if I come across more than one post where there is a video, the screen will start to flicker. Only one video will play, but the screen flickers. If there is only one video on the screen, it is fine.

I can turn off Hardware Acceleration and this will resolve the issue, however, when I go to other sites such as Apple TV or GeoGuessr, the sites lag until I turn Hardware Acceleration back on.

The issue seems to be between Hardware Acceleration and when multiple videos are loading on a page.

I would like to be able to turn off preload of videos (and images) so that I can watch a page with a lot of videos and only load those that I want to see. This is important if you don't have a high bandwith or a lot of data. I am sure I have done this before but now I am not able to achieve that.

Thank you in advance, Virtually yours, David

I get 'you browser cannot play this video" when I try to watch NFL Sunday Ticket on Youtube; what causes this? I use Linux Mint on my laptop.

I also have Opera browser installed; I get the same error using Opera.

Please help. Thanks.

I'm on a Mac desktop, Mac Tahoe 26.6.2, using the latest version of Firefox, although this frequently happened in previous versions. Audio often disappears from videos and reels. When I refresh the page, nothing happens. To get sounds working again, I have to quit Firefox and restart, but by then I've lost the reels I was watching. This is a big issue for me as I am a musician. Any ideas on how to fix this permanently?

I am unable to make or receive video calls in Facebook and WhatsApp. I used to be able to in Facebook. The message I get is that my browser doesn't support video calls. What is wrong?

Постоянное отображение панели задач (до тех пор, пока не нажму на иконку браузера на панели дважды. Повторяется с каждым заходом в режим "на весь экран" ), при просмотре видео, в браузере, в формате "на весь экран" с версии 156.0. в других браузерах подобной проблемы нет, только в Firefox. Прикладываю скрин визуального отображения проблемы. С настройками самой панели задач проблем нет, перепроверял.
