Forum Bashkësie Firefox

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

Good day, I have Firefox 138.0.4 running on Windowx 11 24H2. PC details as follows: CPU = Ryzen 5 2400G RAM = 32GB GPU = RTX 3060Ti 8GB Connection is 50/25Mbps fibre connection

My issue is that when watching F1 from the following site: https://f1tv.formula1.com/, after some time (it differs in how long it takes to manifest), the stream starts to stutter. Note, it is NOT buffering, it is like the stream gets "stuck" or freezes for an instant then continues. The "freeze" then becomes more frequent and sometimes even lasts for about 2 seconds before resuming. The most important fact about all this is that this does NOT happen when using Google Chrome, hence my suspicion that it is somehow related to Firefox specifically. Does anyone have any idea what is causing this and/or how to fix it, please?

Hallo everyone,

after many hours of Google search and trying many changes in the "about:config" section im done with things to try so my last chance is here.

The problem i have is that videos dont play if i mouseover the firefox window or tab i.E. on the windows taskbar. The video will only start to play if i click on the window/tab and that window/tab is the "active" one im looking at.

It worked fine before but some firefox update f***ed this up (and yes the official firefox updates are the only thing that changed), no i dont know which update it was because i didnt recognize the problem right away.

The autoplay option is set to allow media and audio.

The weird thing is that when i open a video in the vlc player and do the mouseover, everything works just fine. So my conclusion is that some setting was messed up on the new firefox version.

Some data of my pc, everything is updated: - Windows 11 Pro - CPU is AMD Ryzen 7 5800X3D 3,4GHz - GPU is AMD Radeon RX 7900XT - RAM is 32GB DDR4 CL16 - Internet is wired connection with 250K speed - Firefox Version is 137.0.1

Sorry for my bad english and thank you in advance.

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.

Hello people,

Please some help around the following issue, since a few days, Firefox will not play mp4 files directly in the browser. What it does when clicking to open an mp4 from the file server, it saves the file first and then opens a window to play it. Or it directly provides the save dialog window instead of playing it in the browser window directly.

Any ideas, appreciated. I have a lot of files to assess for my students, and this browser behavior makes it very tedious.

Greetings.

This problem started yesterday. The sound in YouTube with Firefox is extremely low. As far as I can tell, the problem doesn't exist elsewhere. Other browers are OK with YouTube and other websites that have sound are OK with Firefox.

I reinstalled Firefox and rebooted the computer - still has the problem.

I'm using Windows 11 24H2 (home) on my desktop.

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.

Initially connects video playing to Headphones via Bluetooth then audio stops. Reloading doesn't help. But the same works perfectly on other browsers. Problem is with Firefox audio setting. The problem started only a week ago for firefox

Since the last update, I believe, because this error occurs constantly and with EVERY video. This is often, not always, the case immediately after updating FF. Now it was fine for a while, but now it's so bad that I'm having trouble watching YT videos properly. Reason: Browser open, logged in to YT. I click on a video to play - video opens, plays maybe 10 to 20 seconds, then playback stops spinning top, I also found out during the last glitch after update that if I switch the resolution briefly, higher or lower doesn't matter - important is to leave the current resolution and switch to another one. And oh wonder - immediately, instantly with the change, the video starts playing. If I wait for this - without doing anything myself, it sometimes takes 30 - 40 seconds for the video to start ... sometimes it just "hangs" ... This is extremely annoying - if it doesn't work, I have to switch browsers... What is also extremely annoying is that it occurs almost regularly after an update ... until the next one possibly, for unknown reasons, does not fix the error, but sometimes mitigates it. Now, however, the disruption/interruption is so massive and totally annoying that I'm thinking of switching. I'm just tired of it ...

MP4 Not loading:

I have uploaded a few MP4 animated images to our website, but they are not loading in the Firefox browser. It looks like they are getting corrupted. This issue only occurs in Firefox. I’ve also attached screenshots for reference. Can someone help me understand why they are loading like this?

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.

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.

Video files won't play on the msn.com website; the same videos will play on another browser, but not on Firefox. What do setting I need to change?

Thank you.

Hello,

Sorry if this is not the right place to report this, this is my first time and im lost between all these 3 different pages "Discussions/Support/Bugzilla".

The latest Firefox (v137.0) update for Windows 11 that I installed today broke something possibly related to DRM-protected content, at least for me. Now whenever I start streaming live sports, the video always plays in the lowest quality (possibly even lower than the lowest option available in the player, for some reason?).

I tried to restart my PC, clear the cookies for that streaming website, disable all my extensions, but same issue. On my other browsers everything works fine as always, so only Firefox got broken after this last update.

I have both of these options turned ON even before the update: - Use recommended performance settings (Hardware acceleration). - Play DRM-controlled content.

Why do I think it's related to DRM? Because I can now record and take a screenshot of the video, unlike before the update where it always turned into a black screen.

Help please!

Can't seem to stream Netflix. Firefox is up to date. New Widevinecdm update today 4/2/2025. Apparently since that update (today) I can't stream. I get Netflix error code F7702-1003. Searched/read several FF articles/forum Qs - no help. did a "refresh FF" - no help. don't want to install Chrome (Google knows too much about me already). Netflix worked fine last night. Tried unchecking "play DRM controlled content" - FF(Netflix site) asked to enable DRM - clicked ok - reinstalled. no help. Hard reboot - no help. Still running a Win7 64-bit desktop OS - works fine.

HELP!! Thanks

Yesterday I updated Firefox to version 115.22.0esr this morning when it was released. Have never had any problems viewing video on Netflix but now I am getting Netflix error message F7702-1003. Yesterday I asked "what can I do? I've rebooted computer as Netflix says and it didn't help."

Today, to see if the issue was a bug with version 115.22.0 esr I logged onto both Peacock and Hoopla to try to stream video. On both sites the same thing happened that happened on Netflix. I log into the site, select a video, and when I try to play it I get a message that "widevineCdm plugin has crashed" and video won't play.

Since this problem just appeared after I updated to version 115.22.0 esr it seems likely that there is a bug in this version which is crashing the plugin and preventing streaming video. I note that I can stream some video having checked both YouTube and an online television station.
