When I try to watch youtube, firefox will repeatedly rotate from portait to landscape. This is not what I want and there are no settings I can find to stop this. I cannot find a solution anywhere. I would like to view content the way I want, not landscape just because it is youtube.

I just upgraded Firefox to version 156.0.2.

It no longer plays mp4 content from a website. It says "No video with supported format and mime type found".

This used to be OK.

Hello, I need the player's audio to keep playing while watching a video in the browser—essentially allowing two audio sources to run simultaneously. I have already configured all the necessary audio settings in both the player and the system.

Videos autoplay using iPad Pro M5 despite Auto-Play Video Previews, Auto-Play Animated Images and Auto-Play Message Effects all being turned OFF. Current Mozilla advice appears to be associated with PC use not iPad. Thank you!

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.

After a Windows 11 update, every time I play some video/sound and stop the playback, my whole computer audio doesn't work anymore. When I reset my computer, the audio comes back again. I tried using other browsers (Edge, Chrome, etc.) and other programs/applications, but this only happens in Firefox.

Any ideas on what can I do to solve this issue?

Basic information:

Firefox version: 133.0.3 (64-bits) Operation System: Microsoft Windows 11 Home Single Language OS Version: 10.0.26100 Compilation 26100 Computer Brand: Alienware m16 R2 Sound drivers: Realtek Semiconductor Corp. version 6.0.9738.1

From time to time, when while playing YouTube Premium videos in Firefox on my Android Galaxy S26 (same was on S24 before for years) I connect the phone to Android Auto of my Ford Mustang 2024 with USB cable, the playback stops. After that I still can browse the web, but can not play any video until I twice in a row kill and restart the Firefox (loosing all private pages, etc). Disconnect/reconnect of the cable does not help. There are no any errors reported when it happen. It looks as some connectivity or YouTube problem, except the moment I restart Firefox twice everything goes back to normal. Since during that connection the audio is getting redirected to the car speakers, I suspect the problem may be audio-related, but I have no specific evidences. Also since car's multimedia is usually still booting at the time, it takes Android Auto several seconds to start, and I guess some random delays and/or transient errors might happen during that period, that I guess may be not handled properly by Firefox, making it leak some critical resources.

Sometimes (extremely rare) I experience similar video hangs just when switching between YouTube videos without any connectivity changes, but that may be some different issue.

Hello,

I am a new firefox user and would like to use it 100%, but have been running into a few bugs. This one I have been unable to find this issue myself, so thought I would ask here. I use Qobuz to stream hi-res music up to 24bit/ 192kHz. Some albums do not have sound at that resolution. The file will load and timer shows the song is playing, but there is no audio. I can change the setting to stream at 16bit/44.1kHz and then I get audio. Again, this does not occur with all albums, some will stream at hi-res and some will not. An interesting note: the same file with no audio at hi-res on firefox will have audio at same resolution setting on chrome. The only thing I can think of is chrome is reducing resolution in the background, or maybe a DRM issue? I do have "Play DRM-controlled content" checked in firefox settings.

p.s. I am aware that streaming music through a browser is not necessarily the best way to listen to hi-res music, and my ears may, or may not hear the difference between the 16bit and 24bit. However, the issue is the functionality, or lack of.

Thank you in advance for any insight.

Hi,

I have been having this weird issue that I believe is being caused by firefox as no other internet browser has the same issue. When I'm playing music on spotify and I open firefox the sound goes quite bu the audio is still playing on spotify . One work around I have found is to take on of the tabs and use it to open a new window and the put it back with the others and the sound comes back again. I lost and need help as this is making it hard to want to use firefox which I have been a user of since it first came out.

I recently started having this issue with YouTube in the mobile Firefox browser where if I tap within the video frame (anywhere on the picture) the video pauses/plays just like clicking the video frame on desktop. Before when I tapped the frame it would toggle the overlay play menu with the usual play/skip/settings but the video would continue playing beneath the buttons. To clarify, the play menu always disappears like it should when the video is playing so this is not the "Accessibility player" settings issue.

The issue goes away if I sign out of YT which makes me suspect it's an account settings issue, however I have played with the accessibility and other settings to no avail. I have uninstalled/reinstalled all of my extensions, restarted my phone, signed in and out of youtube/firefox, updated everything, uninstalled and reinstalled firefox, no solutions so far, please help!

Hello. On/about 25jun2025 the sound on my Firefox videos stopped working from any source. I know enough to determine the problem is on Firefox. Videos on MS Edge worked fine. Sound works form VLC songs, etc. Sound does work with earplugs. Wondering if that could have caused the loss of speaker sounds. You think I could delete my current firefox and reinstall it. That would be a pain (an hour or so to set it up again.) Thanks, Bill

After updating firefox from 128.8.0 to 128.9.0, no embedded videos will play (youtube, instagram, plex, etc...)

The only way to get them to play is to run the browser in troubleshoot mode. Even a fresh browser profile doesn't work. Disabling hardware acceleration also does not work. Tried firefox 137.0.2 and that also does not work. Downgraded back to 128.8.0 and videos play flawlessly again.

I'm running firefox on gentoo linux on a thinkpad x13s (arm64) which uses Qualcomm Adreno 690 graphics.

Anything I should try would be greatly appreciated. Thanks.
