Firefox: форум сообщества

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

I've recently decided to return to FF. On the whole everything is going fine, except for streaming. I often use my provider's site (nostv.pt) to watch some games, races or shows. However, every time I do, I'll get backwards skips every now and then where the stream goes back 1-2s. Usually the second time this happens the stream detects I'm no longer live and I can skip ahead to real time, but this is annoying, especially when watching games. During a 2h stream session this will happen around a dozen times.

So I would like to know if there are other people with the same issue or what I can do to prevent this from happening.

Having issues with my Bluetooth AirPods and sound in Firefox. The problem being there is no sound when the device is connected and watching a YouTube video for instance. Things went wonky after the recent update to 133.0.3. At first there was no sound period. Then somehow, not even sure how, I saw that Firefox was muted in Windows (11 Pro) settings. That's a mystery unto itself since I'd never previously gone to that area. Now that I have volume through external speakers working, audio through AirPods doesn't. Everything works fine using Edge and audio from music. I know the device is connected and when that is, it's the default for where sound comes from. Used the test thing and yup there is audio. Is there something I'm missing? There must be but I can't figure out what it is. Hopefully someone reading this can point me in the right direction of resolving this issue. Thank you in advance.

thanks for firefox

but why: won't play audio https://wordcat.de/wp-content/uploads/2024/12/test-video-simplescreenrecorder-2024-12-22_opus.mp4

will play audio https://wordcat.de/wp-content/uploads/2024/12/test-video-simplescreenrecorder-2024-12-22.mp4_mp3.mp4 (bigger in filesize)

why? WHY????

This is the link to the video that will not play in FireFox. https://www.swingtechnologies.com/UploadVideos/clarkj@pobox.com/S200629_019 B.mp4

When playing YouTube videos in fullscreen mode, the video appears to skip as would be expected with frame drops. However, with stats for nerds open on the videos, no frame drops are reported and buffer health is fine (40+ seconds).

I'm on an up to date version of FireFox, I've tried with hardware acceleration both enabled and disabled, I've tried opening task manager to see if system usage looked weird (it doesn't, although it's not like I can have TM running while the video is playing in fullscreen so hard to tell) and am at a complete loss. All drivers for CPU and GPU are verifiably up to date (did full system check three days ago) and the only conclusion I've been able to come to is that it must be either a problem with FireFox or a problem with YouTube. I've seen no recent reports on any of the forums that I can find pointing to either as the culprit. So if anyone has any further ideas or solutions, I'd love to here them.

For the last maybe 2 weeks of so I have been able to play videos on any website,it is only Firefox that is having the errors. I use Windows 10, and the only extension I have is password managment

I have tried: 1) troubleshoot mode: no changes 2) clearing cache: no change 3) making a new Mozilla profile: no change 4) lowering/turning off security protections 5) refreshing from uninstall 6) uninstalling and reinstalling 7) Allowed autoplay of media 8) toggled off drm

The primary sites that I use are; HBO - error 1K-003 Twitch- error#4000 Patreon- doesn't error out, but just goes black on player Dropout.tv- player error YoutubeLive- Browser error

youtube goes fulscreen but not in the richt way i can see the video fully but it does not cover my sreen fully an the under part of my screen it is not posting see image for a better picture

I am using Latest version of Firefox (139.0.1 - 64 Bit). I have tried the "hardware acceleration" option on/off and Safe Mode as well. None of it can make Prime Video, Amazon Music or Spotify work! Surprisingly, the podcasts work in Amazon music but not the songs.

I am able to use these in Chrome.

Thanks in advance for the possible resolution steps!

I'm facing an issue where videos on various websites do not load properly when I'm using Mozilla VPN. The issue is happening on platforms like YouTube and streaming services. The videos either don’t start, or they buffer endlessly, even though the internet connection is stable. This issue only happens when the VPN is turned on, and the videos work fine when the VPN is off.

I’ve tried troubleshooting by disabling the VPN and clearing my browser cache, but the problem persists.

Could anyone provide a solution or explain why this is happening? Any help is appreciated!

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.

We're finding we can no longer watch FUBO TV on Firefox. Works fine in Edge. Anyone have any suggestions? We've cleared cache/history, restarted laptop, etc. This occurs both on recorded programs and live tv. We still seem to be able to get the commercials, although we tried watching on two different devices and the commercials were very different. Is it possible for Firefox to have been hacked but not Edge on the same device? Doesn't sound plausible to me, but I'm not sure. This has happened since the last update to Firefox. We have Windows 10 64 bit. Firefox 134.0.2 or whatever the latest version is. We're stumped why it works on one browser but not the other. Has to be a Firefox issue.

The video from certain sites(not one, but multiple ones) plays as gibberish. Attached a sample from amazon prime. Tried the following

• System restart
• Bios/Firmware update
• Display driver update
• Windows refresh

The issue seems very much localized to Firefox and not seen in any other browsers.
