Firefox Community Forum

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

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.

Media resource could not be decoded, error: Error Code: NS_ERROR_DOM_MEDIA_DECODE_ERR (0x806e0004) Details: virtual mozilla::MediaResult mozilla::FFmpegVideoDecoder<62>::DoDecode(mozilla::MediaRawData*, uint8_t*, int, bool*, mozilla::MediaDataDecoder::DecodedData&): avcodec_send_packet error: Unknown error occurred

AV1 Hardware Acceleration stopped working. In about:support->Media->Codec Support Information Firefox states that Harware Decode AV1 is supported but it uses only Software Decoding. AV1 worked perfeclty before in Firefox, is still working in other browsers and apps in my system.

First of all I'm doing my testing in:

AMD Ryzen 7 7730u Windows 11 24H2 Firefox 133.0.3 Haylou GT1 Pro Bluetooth earbuds

I'm using jellyfin on web. And I listen to music on it, the problem I'm facing is... The moment I disconnect and reconnect my earbuds, the audio stops, the tab says "PLAYING" but no audio is played, I can press pause and play an infinite number of times but does not work UNTIL I reload the tab, then the audio comes back. Wouldn't be a big deal except for the fact everytime I have to reload, jellyfin does not save the current playlist so I have to create it again.

I tested this on the latest version of Microsoft Edge and it works with no problem there, I disconnect earbuds, audio stops, reconnect them and audio resumes, without even having to press play. The problem is something with firefox and the way it selects audio devices I guess?

I send a screenshot of firefox with the tab "PLAYING" but not actually doing it, and I send a logging file that I created using about:logging and the preset "Media playback", starting when I play media, disconnect bluetooth device, reconnect and can't hear anything

Logging file: https://pastebin.com/8CXn7bkv

If you need more info, please tell me. Greetings!

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.

Asking after trying way too many things FIREFOX 135.0.1 (64-bit) lates version and fully updated.

Playing Youtube Videos fails as the video keeps loading forever.

It happens randomly but often. It could happen trying to play the video the first time (keeps loading forever) or if the video is playing ok and you try to search any frame in the video or jump some time in the video, the frame stops and keeps loading forever.

I suspect it could be an extension because if I use Firefox in troubleshooting mode it works. However I tried to disable extensions one by one until none was enabled and still fails. Tried all options in the proxy. BRAVE works ok (but I installed it fresh to check another browser, I still prefer Firefox)

The issue happens only on Youtube. Youtube premium. Images attached of an example video that got stuck and loading and the list of extensions that I have, I tried to DISABLE ALL thes EXTENSIONS and still fails (???)

I got this new Chromebook, and now I'm having issues using YouTube. When I select a video to watch, a message pops up at the top saying "To play video, you may need to install the required video codecs." I am able to watch the video I selected anyhow, with some minor issues with the picture and its frames I believe, however, when I try to watch a different video, it does not work. Sometimes it will play for a short bit, but will then stop, and start buffering. When I then refresh the page, the video will not play and will only buffer. I am not sure what to do, and if this is an issue with the browser, or the device itself, please help?

Hello I am using Google Flow on my Linux PC and when going to edit scenes I get an error about a missing Codec. If I use Brave browser works fine so this makes me think this is not an OS issue but browser.

For the past month, out of the blue, I have been unable to play Spotify via my web browser. After troubleshooting with Spotify chat, it seems the issue is actually Firefox, because if I choose to play it via the app installed on my computer, it will play, but not via the web browser.

It was display "Spotify can't play this right now".. then it will skip through three songs, play ads & then will play the first 10 seconds of audio of the next song & then it will cut out.

Anyone else experiencing issues with Spotify via the Firebox web browser?

Здравствуйте. Последнее время заметил следующую проблему. При открытии некоторых сайтов, где есть видео или транляции, колесиком мышки открываю нужные видео или трансляции в новых вкладках. Ситуация следующая. Если не спеша открыть несколько вкладок, например 5, после перейти к ним, то нужно нажать в центре видео/трансляции "плей", чтобы видео стало работать. НО, если открыть вкладки (так же 5 или более) и сразу же переключаться на них, то видео будет автоматически стартовать. Раньше так и было при добавлении нескольких вкладок с видео, а после переключения на них, видео сразу открывалось. Теперь - нет. В настройках ничего нигде не менял, проверял как на версии браузера для пк на 133..., так и на последней 137... Отключал все дополнения, в настройках сайтов давал разрешение для автовоспроизведения аудио и видео. Хочу отметить, что такая проблема на многих сайтах. На некоторых же всё работает как и раньше. Также отмечу, что переустанавливал браузер с полной очисткой. Железо у пк хорошее, озу 32 гб. Никогда проблем такого рода не было. Прошу помочь с решением проблемы.
