Firefox Community Forum

I have noticed that just recently videos across all different websites are not displaying properly. The image part of the video is a green scrambled mess. The audio is fine, but the images are wrong. I am not having this issue on a different browser, and I'm not sure what I'm supposed to do. I don't know if changing any of the settings will help or if there's a bug in one of the updates.

I cannot select 8K60fps Youtube playback on my M4 Mac mini, so please add support for this in the Firefox MacOS browser for Apple Silicon devices, or at least the latest M4 series of chips.

I decided to download Firefox and make it my default browser, so I downloaded it and followed some recommendations I found online for configuring security settings...but for the life of me I can't remember what those are.

Weeks later, I decide to watch Peacock, but the error message says I need to disable my ad blocker. I search for an ad blocker in the extensions but can't find one, so I start disabling other extensions like Facebook Container...but to now avail. I follow all the usual online steps--clearing my cache, restarting the application, restarting my computer, etc--but nothing works. I have the same error with Netflix, and switching to another browser yields the same result. So it must be something wrong with my system.

Can you help?

I have a Microsoft Surface Pro 8 with a Slim Pen 2. I do a lot of searching in google maps and have noticed that I can access google maps and can use pinch to decrease and expand the maps and if I open a street view I can use touch to move the field view around as it should be. The problem occurs is when I use my slim pen. Once I have used the slim pen to move a field or open a street view the touch capability stops working. I can still close the window and other things with the touch capability (system type functions), but within the browser it's disabled.

I have not noticed this occurring in any other web site or type. For example I can go to amazon and interchangeably use the pen and touch capability without issue.

I have tested this in Google Chrome and MS Edge and it does not disable the touch capability when I use the pen.

hi

i need help with a website that used to play videos but since last few times its not working as its saying video cannot be redirect to due to cookies but i clear them so can you help

I cannot seem to get playback with Firefox browser for either Tubi TV or Pluto TV anymore. Have uninstalled and reinstalled Firefox, have tried to just refresh data yet still no playback.

Audio doesn't work with Firefox. This appears to be ONLY a Firefox problem. Headphones work with Edge. Computer speakers work. In Windows settings, testing audio works. But when I attempt to listen to something in Firefox, there is no sound at all.

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

I have no idea how to access the following directions I found trying to address the question of : How to stop videos from following as you scroll down a link huff post …..Firefox 135. Mac 12.7.6

Go to about:config and set media.autoplay.enabled.user-gestures-needed to false to disable all kinds of autoplay.

I've recently done a clean reinstall of Windows 11 and have noticed that, only for Firefox (134.0.2, build ID 20250120135430), a few videos playback without any audio, yet the same videos play with audio when using edge as a comparison. Most (if not all) of these videos did play with audio in Firefox prior to this reinstall.

Firstly, I'm pretty sure this is not a windows sound mixer issue since many videos on the same page and tab play back with audio just fine in Firefox. The same goes for it not relating to the Firefox setting 'Speaker selection', under (burger) > settings > privacy & security > Permissions because videos of different formats (or using different players) on the same page play back audio fine. The tab is not muted. Again, some videos on the same browser tab play audio fine; some of a particular format or player only play the video, while missing the audio (and where Edge plays the same video with audio).

Another common and potentially relevant issue I've seen is that, this being a 'Windows 11 N" install, it was initially missing the settings > system > optional features > Media feature pack, but that is now something I've successfully added. I should add that windows did report problems when I initially tried to add the media feature pack but, after a very long delay, it eventually appeared to succeed when I ran a couple of DISM incantations that I think ended with - "dism /online /add-capability /capabilityname:Media.MediaFeaturePack~~~~0.0.1.0"

I have the 'Play DRM-controlled content' setting enabled.

Comparing the Firefox vs Edge video playback on this video test page - https://tools.woolyss.com/html5-audio-video-tester/ I get the following results (don't know how to get it formatted/aligned correctly, sorry) -

                           FF vid    FF audio    Edge vid    Edge audio
av1-opus-sita.webm          Works     Works       Works       Works

avc-mp3-sita.mov            Works     Works       Works       Works

And perhaps also relevant is that there's also a difference in the audio-only samples further down the table on the same page -

                   FF audio   Edge audio
audio-sample.mp3    Works      Works
audio-sample.weba   Works      Works
audio-sample.ogg    Works      Works

ac192.mp3           Works      Works
spoonradio-hd.aac   FAILS      Works
audio.opus          Works      Works

Also, every 'v.redd.it' / reddit-video-player video plays the video fine but has no sound when using Firefox but plays both sound and video fine with Edge. Here's one for example - https://old.reddit.com/r/funny/comments/1i7y1nr/rock_paper_scissors/

I've seen lots of similar (but not identical) issues on Firefox video with no audio problems with suggestions a few things to try. In addition to what I've already mentioned above, I've tried the following without success -

- Restarting Windows - Restarting Firefox - Restarting Firefox with addons/extensions disabled - 'about:support' > Refresh Firefox - 'about:support' > Clear startup cache - (hamburger) > more tools > task manager > (click the little profile icon for the page playing the video) - I've checked the settings suggested here: https://support.mozilla.org/en-US/kb/fix-common-audio-and-video-issues#w_check-some-firefox-settings

I realise it may be possible to side-step this problem by flailing around with more drastic work-arounds like trying a clean re-install of Windows or a full uninstall and clean of Firefox, but that doesn't really help figure out the problem, which leaves the possibility it could easily happen again to me or others when it might be something that can be more properly fixed or guarded against in Firefox itself, so I hope someone can suggest what might be done to home in on identifying the cause of the problem and so learn whether a more precise fix can be employed.

My GPU is the integrated GPU on the Intel U7-155H CPU. When some AVC videos are played, the browser reacts extremely slow and the video image is glitched and at a really low rate of frame, and the video decoding engine seemed to be 100% occupied as shown in the task manager (normal video playback never occupied so much of it). Seems like AV1 encoded video never triggered the problem. The problem doesn't always happen, but at a rather high frequency. This never happened before I updated the Intel graphics driver from 32.0.101.5972 to 32.0.101.6129. The problem seemed not to happen on other browsers such as Microsoft Edge.

Can you guys check why your netflix account is getting logged out every time regardless of how many times you logged in and for prime video if you play any video i'm getting video player error, can you please check

I've been searching for an answer to this for weeks to no avail. It concerns YouTube videos "autoplay"ing on YouTube. Many have asked this question and most responses state to shut off Autoplay. These are two separate issues. AotuPlay means the next video on YouTube will advnace automatically requiring no user input. If Autoplay is off, streaming stops at the end of the video. The issue I am having is when I open a YouTube video to a new tab (but do not switch to that tab), the video WILL start playing as soon as that tab is in focus. This never used to happen and indeed, on two other computers with the settings and extensions all sync'ed, this doesn't happen, except for on this one computer. Today I found someone that posted the exact same problem 5 years ago and didn't get an answer. He seems to describe it well:

1. Okay, so before, when I loaded up 100+ Youtube videos, they stayed when switching tabs - no autoplay. Suddenly they decide to autoplay when switching tabs - note, I've not done anything to my settings or plugins. Fair enough, maybe you changed something (which you often do, without informing). So I check the options. It was on "Block audio", which obviously didn't work, so I tried "Block Audio and Video" - which WORKS, but now both the video is paused (which I want) AND the audio is set to mute (which I DON'T want) - so... what does it take to have Youtube wait for a click to start playing a video loaded in a background tab, but KEEP AUDIO ACTIVE, so I don't also have to unmute the damn video?

One person posted a possible solution: Maybe check this pref on the about:config page.

   media.block-autoplay-until-in-foreground 

This setting describes the issue kind of. If you have this set to false, the moment you send a link to a new tab, YouTube starts playing in the background. Setting it to false keeps the video paused until that tab is in focus. That is how mine has always been set. What I am looking for is a setting that would say something like: "block autoplay until play is pressed"

Thanks in advance and sorry for being so long-winded

For many years, I have been exchanging video calls on Facebook.

Recent attempts to video call the same person I've been video calling for the past 3 years result in "your browser doesn't support video calls"

Have I been "hacked"?

Please explain.

Could a real person answer this question for me, please? Thank you.
