i will be happy if you can guide me on how to enable it. because tbh Firefox are my daily drive

Lately, whenever I click into a youtube video from within youtube, instead of Firefox blocking autoplay, it mutes the video but lets it play.

Initially, it was muting EVERY video I pulled up, but messing with my settings has fixed the problem if I click into a youtube video from elsewhere (ex. a google search result), or if I refresh the page. It's super annoying to having navigating youtube be this non-functional right now, though, since everything just silently plays until I catch and unmute it! Any help would be super appreciated!

(I'll attach an image with my current autoplay settings.)

Whenever I hold down the mouse button or space bar to speed up a video by 2x, it seems to let out a small crackle / pop, it wouldn't be as annoying if it only happened one time but it happens practically anytime I do it, sometimes it's when I first press it down, and sometimes it's when I let go.

I've been using Firefox for years and never had this issue until like 3-4 days ago I'd say, and it's a small thing but it adds up constantly and makes the experience fairly annoying, I tested the audio on google chrome extensively and it doesn't seem to happen there so I have to assume it's a Firefox issue.

Would love to see if there's a way to fix this.

Please help me as i want to record some gameplay but it keeps getting squished & it is pissing me off. I have asked on reddit & people were unhelpful & telling me to just buy another computer. this is annoying as it is causing me when playing games it causes text to be unreadable at times. Thanks in advance.

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

It was working fine until the day before yesterday. The volume of the speaker got low before it stopped working. The PodCast and Vimeo are working fine. So it is not the problem of my computer speaker.

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?

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.
