Firefox 社群討論區

Hi,

two days ago, video embeds on Twitter stopped working in Firefox. Please help me troubleshoot the issue, so that I can either fix it myself, or present enough evidence to file a proper bug report.

Affected version: FF 140 ESR. I had some 140.7 installed when the error first happened, but have upgraded to firefox-esr_140.10.1esr-1_amd64 since. Didn't fix the problem. *Not* a snap package, regular .deb!

Affected OS: Ubuntu 26.04 LTS, not a fresh install but upgraded from 24.04 instead (which itself was upgraded from 22.04).

Symptoms: Videos on X (and Facebook) no longer play, the preview image is there for a split second, then an error appears. Video on for example Youtube is fine, though. Local players like VLC also do work as expected. Video on X worked under 26.04 before this happened.

The issue likely started when removing surplus packages and metapackages from the upgrade. According to synaptics, this is the complete list of packages removed: augeas-lenses bomber bovo clevis clevis-luks db-util db5.3-util dolphin-dev gir1.2-freedesktop-dev gir1.2-glib-2.0-dev girepository-tools gostsum granatier guestfish guestfs-tools guestmount icu-devtools jose kapman katomic kblackbox kblocks kbounce kbreakout kdegames kdegames-mahjongg-data-kf6 kdiamond kfourinline kgeography kgeography-data kgoldrunner kigo killbots kiriki kjumpingcube klickety klines kmahjongg knavalbattle knetwalk knights kolf kollision konquest kreversi kshisen ksirk ksnakeduel kspaceduel ksquares ktuberling ktuberling-data kubrick kubuntu-web-shortcuts ldmtool libaom-dev libarchive-tools libaugeas0 libblkid-dev libconfig11 libdbus-1-dev libdlt3 libffi-dev libfmt-dev libfontconfig1-dev libfribidi-dev libgd-perl libgio-2.0-dev libgio-2.0-dev-bin libglib2.0-dev libglib2.0-dev-bin libgraphite2-dev libguestfs-perl libguestfs-tools libguestfs0t64 libharfbuzz-cairo0 libharfbuzz-dev libhivex0 libicu-dev libjose0 libjson-glib-dev libjxr-tools libjxr0t64 libkdegames6private6 libkmahjongg6 libldm-1.0-0t64 libmosquitto1 libmount-dev libosinfo-1.0-0 libosinfo-l10n libpcre2-dev libpixman-1-dev libpolkit-gobject-1-dev libpsl-dev libpwquality-tools libpython3-dev libpython3.14-dev libselinux-dev libsepol-dev libspdlog-dev libsqlite3-dev libssh-dev libstd-rust-dev libstring-shellquote-perl libsys-virt-perl libsysprof-capture-4-dev libsystemd-dev libtirpc-dev libusb-0.1-4 libusb-1.0-0-dev libusb-1.0-doc libusb-dev libvirt-common libvirt0 libwebsockets19t64 libwhoopsie-preferences0 libwhoopsie0 libwin-hivex-perl libx265-dev libxdo-dev libxdo3 libxft-dev libxkbcommon-dev libxrender-dev libyara10 lskat lskat-data mosquitto mosquitto-clients native-architecture osinfo-db palapeli palapeli-data picmi qml6-module-org-kde-games-core skladnik supermin whoopsie whoopsie-preferences I don't think they are related (libx265 and libaom are only the -dev packages), but this is the only system-wide change on that day that I can remember. I of course tried re-installing these, but this also doesn't fix the problem.

On my journey of fixing this myself, I also asked the all-hallucinating knowledge randomizer frontend of OpenAI, which made me check a couple generic spots on my system and in FF itself.

I have HDR working in Proton games and mpv fine (using Plasma 6.4 / Wayland)

I enabled HDR in Firefox (gfx.wayland.hdr), and HDR content works in YouTube fine ( looks amazing!) however.. I have an issue in that all non HDR content doesn’t show any video (I have sound) just a green sceen (see screen shot) including all ads.

Any idea how to work round this ?

I have AMD 7800 GPU .

Cheers

I am using Firefox on gnome desktop on the PureOS variant of Debian. About three days ago, I went to listen to my Spotify playlist on Firefox, not through the Spotify app. I had no sound, checked my system settings and turned the volume for Firefox from zero back up to normal. The rest of the song played, but when the next song came on, again no sound. I watched the sound settings and when the song finishes, Firefox disappears from the sound settings list. When the next song starts, Firefox is back in the list but volume is set back to zero. I suspect this may be something in gnome, but I thought I would check here in case anyone else is seeing this issue. Thanks so much for any help or at least a shoulder to cry on :D

Since Flathub list the org.mozilla.firefox app as official, i hope this is the correct support channel.

Recently i switched from distro specific package managers to flatpak as my application provider. The firefox flatpak won't play most embedded Video/Media on applications like in-browser fediverse clients, forums, blogs or wikis. Youtube works without any issues, Twitch is fine until there is an adbreak. Then it sometimes stops with the supported format/mime error (screenshot appended), only recoverable by cache-dismissive reload.

I used this Article https://support.mozilla.org/en-US/kb/audio-and-video-firefox and the links it contains to debug without any success. None of these samples play. just shows supported format/mime error https://test-videos.co.uk/bigbuckbunny/mp4-h265 At this test website 1. and 3. example won't play. I provided a screenshot before and after trying to click play on all the examples. https://www.tekeye.uk/html/html5-video-test-page

Contrary to the observed behavior about:support#media claims Software Decoding supported for everything except HEVC.

Chromium Flatpak has no such issues. So i copy the video url and play it with chromium. You can see: dire times.

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.

I recently updated my browser, and I've noticed that while listening to music on YouTube, for some reason, the volume slider within the player also controls the stream volume within KDE Plasma's volume mixer, making for a much more frustrating experience. Now the volume resets to what was set on YOUTUBE rather than sticking to what was set in the VOLUME MIXER every time a new video plays or any time the page refreshes. This means that the volume gets reset every. single. time. The issue with this is not only that YouTube's volume slider isn't as accurate as KDE Plasma's, but also that a media player in a browser shouldn't be controlling its own system volume within the mixer because it causes issues and frustrations like these.

How do I separate player and stream volume?

Here's my inxi so you can see what I'm using/what I'm on: ```text System:

In Firefox, I have audio and video autoplay blocked globally, and added an exception for one particular website (Discord). However, Discord now only autoplays videos once, but doesn't loop them as it should (they implemented GIFs as videos, but now they don't loop).

Of course this could be interpreted as a bug in Discord's web client. However, there shouldn't be a difference between a website that got an exception and autoplay being globally allowed. Therefore i suspect that there is a bug in firefox where some property, state, or hint is set differently depending on whether a page has been added to exceptions or autoplay is allowed globally.

Is there anything i can do to work around this? I really want an autoplay exception to actually work as expected (the website doesn't need to know that it's special)

Trouble with streaming services(like youtube(only streams ), twitch, music streaming) on nightly Firefox Nightly 145.0a1 (2025-10-11) (x64) Cachy OS Binary from firefox.com

Since yesterday Firefox stopped working with Crunchyroll and Hidive and says, "Firefox is installing components needed to play the audio and video on this page. Please try again later."

150.0.1 (64-bit) Bazzite Linux 6.19.14-ogc1.1.fc44.x86_64 bazzite-gnome-nvidia-open:stable v44.20260501.1 Widevine plugin is version 4.10.2934.0.

Additionally, I've disabled extensions as well, cleared the cache. I've disabled play DRM content and restarted the browser before turning it back on. I've changed from my own dns server which I see nothing being blocked to google public dns and saw no difference. Everything was working fine on Wednesday night and stopped on Thursday.

For a couple of days now Instagram linked videos won't play here. Actually some of them will -- my own reels and anything linked with that button that looks like a movie 'clapper'. But videos that show the triangular arrow pointing to the right, nothing happens when you click. Not sure if this is a FF issue or maybe something changed at Instagram. Did a google search and nothing came up.

Trying to run Prime and Netflix in a Linux browser on my new Lenovo Chromebook Plus 14. Not that this is an ARM based unit (Kompanio Ultra 910).

I can successfully download Firefox for Linux: Mozilla Firefox Debian Package mozilla-deb-1.0 144.0 (aarch64)

But when I go to run streaming video services get: Prime Video is incompatible with your current operating system or web browser. You must update to watch Prime Video titles. Review the Prime Video system requirements. If the problem continues, please contact Amazon Customer Service and refer to error 7132.

Same with Netflix.

any ideas, thoughts, solutions?  :)

Cheers.

Only on firefox, the music on apple music keeps changing volume. I can hear it sound fine for a second but then it changes the volume to around half of what its meant to be. I dont see any settings to change it, its fine on other browsers, im genuinely unsure of what to do.

I am using Pop OS. Videos are not playing in firefox. In youtube it shows loading infinitly. In reddit all videos become green. I tried playing a downloaded video it also become green. These are only happening in integrated mode. If I use hybrid graphics mode all works good. I attached the about:support page and about:config page.

about:config page link about:support page

These files are taken in integrated graphics mode.

I am running Firefox 144.0 on kubuntu 24.04.3 LTS I have lost sound on Firefox. I have opened the same sites in Chrome and the sound is working fine. It's only in Firefox. I have tried several sites including Udemy, YouTube, and radio programs, no sound from Firefox. The problem started in the middle of a Jit.Si session. All of a sudden the sound disappeared. I thought that restart Firefox would help, then restart the computer would help. But the problem has continued. The speakers is turned on the volume is up, just not a sound from Firefox. What to do?

Make amazon product video work on firefox. I am using fedora 43 kde plasma recently updated. I have a Nvidia video card RTX 5060 ti and using propriety Nvidia drivers Video starts and then stops or after turning off hardware accelaration ran intermitantly then stops. Sometimes telling me the video file is corrupted

Since I updated to Firefox 141.02 I have not been able to play videos on Paramount+ or Netflix. I get an error on the top that says the Widevine plugin has crashed on both streaming services. I have checked that the plugin is on and there are no updates. I am on Ubuntu 24.04. Video on YouTube plays as normal

Greetings! I've been a Firefox evangelist for a long time! I'm having issue with my Dell Precision 5530 pushing Firefox audio to a Bluetooth speaker connected to PC. Others browsers work fine, however FF wants to use the speakers on my monitor, connected via HDMI. I've tried to change several times, however FF does not want to use the BT.

Can you please help?

Thank you kindly!
