Diễn đàn hỗ trợ Firefox

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.

Do you know of a mod that won't allow Youtube to have a resolution higher than 720p, including when embedded? I almost-always have Youtube at 480p when watching through their site. I noticed that when watching a video on another site and that it's embedding Youtube, that the resolution is higher > 480p and in those cases it's not rare to be > 720p.

I'd like a mod or setting so that when it's active that Youtube can't have a resolution higher than 720p, including when embedded. Any idea if there's something alike?

Thank you kindly for your help

FINALLY got my zorin os to update, and now also have the newest version of firefox uploaded and working. My singlefile addon works properly, I have upgraded to the newest versions of my video downloaders, and I have cleared my history, but my 2 video downloaders still don't recognize any videos on youtube. Any suggestions or alternative downloaders?

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.

Hi, when I launch a custom video player on a certain site and go into full screen mode, and then want to exit it through ESC, I can’t do it and the picture freezes. I went to the browser console, and it gave me this error: Uncaught (in promise) TypeError: Not in fullscreen mode

   cancelFullScreen https://interneturok.ru/assets/custom-2dc6965f3c367b4e4590249bd2036dfc.js:578
   hotkeys https://interneturok.ru/assets/custom-2dc6965f3c367b4e4590249bd2036dfc.js:675
   dispatcher https://interneturok.ru/assets/custom-2dc6965f3c367b4e4590249bd2036dfc.js:131|

The technical support of that site told me to write to the browser support, I understood the problem is not on their side. I tried everything and went through incognito mode, the problem did not go away. Give me some advice or maybe the problem is with this site and not with the browser, I also tried to launch this video player through Google Chrome and there were no problems there

This is what the GPTchat wrote about the error from the console: Yes, this error is directly related to exiting fullscreen mode. It says that the custom-2dc6965f3c367b4e4590249bd2036dfc.js script on the site is trying to exit fullscreen when the browser thinks it is no longer in it.

That is, Firefox has already exited fullscreen mode, but the player itself "thinks" that it is still there. Therefore, when you press Esc, the script calls cancelFullScreen(), and the browser throws the error "Not in fullscreen mode".

Plus screen Error

This issue just appeared. Video will not play in Firefox. Windows10 PC, up to date with latest versions, as is Firefox. There is no error message or code. Just the spinning wheel. I see other people are having the same issue but I haven't seen a solution. Any ideas or help appreciated.

Hello,

I recently updated my Firefox browser to the latest version, 138.0.1 (64-bit), on Windows.

After the update, I noticed that when playing videos in fullscreen mode (for example, on YouTube or other video websites), the Windows taskbar (the bar at the bottom of the screen with the Start menu icon) does not hide automatically. This is affecting my fullscreen viewing experience.

Before updating to version 138.0.1, the Windows taskbar would hide correctly when entering fullscreen video.

I was wondering if anyone else has encountered a similar issue with the Windows taskbar not hiding, or if there are any suggested solutions to help resolve this problem.

Thank you for your help!

I've recently done a clean reinstall of Windows 11 and have noticed that, only for Firefox (134.0.2, build ID 20250120135430), a few videos playback without any audio, yet the same videos play with audio when using edge as a comparison. Most (if not all) of these videos did play with audio in Firefox prior to this reinstall.

Firstly, I'm pretty sure this is not a windows sound mixer issue since many videos on the same page and tab play back with audio just fine in Firefox. The same goes for it not relating to the Firefox setting 'Speaker selection', under (burger) > settings > privacy & security > Permissions because videos of different formats (or using different players) on the same page play back audio fine. The tab is not muted. Again, some videos on the same browser tab play audio fine; some of a particular format or player only play the video, while missing the audio (and where Edge plays the same video with audio).

Another common and potentially relevant issue I've seen is that, this being a 'Windows 11 N" install, it was initially missing the settings > system > optional features > Media feature pack, but that is now something I've successfully added. I should add that windows did report problems when I initially tried to add the media feature pack but, after a very long delay, it eventually appeared to succeed when I ran a couple of DISM incantations that I think ended with - "dism /online /add-capability /capabilityname:Media.MediaFeaturePack~~~~0.0.1.0"

I have the 'Play DRM-controlled content' setting enabled.

Comparing the Firefox vs Edge video playback on this video test page - https://tools.woolyss.com/html5-audio-video-tester/ I get the following results (don't know how to get it formatted/aligned correctly, sorry) -

                           FF vid    FF audio    Edge vid    Edge audio
av1-opus-sita.webm          Works     Works       Works       Works

avc-mp3-sita.mov            Works     Works       Works       Works

And perhaps also relevant is that there's also a difference in the audio-only samples further down the table on the same page -

                   FF audio   Edge audio
audio-sample.mp3    Works      Works
audio-sample.weba   Works      Works
audio-sample.ogg    Works      Works

ac192.mp3           Works      Works
spoonradio-hd.aac   FAILS      Works
audio.opus          Works      Works

Also, every 'v.redd.it' / reddit-video-player video plays the video fine but has no sound when using Firefox but plays both sound and video fine with Edge. Here's one for example - https://old.reddit.com/r/funny/comments/1i7y1nr/rock_paper_scissors/

I've seen lots of similar (but not identical) issues on Firefox video with no audio problems with suggestions a few things to try. In addition to what I've already mentioned above, I've tried the following without success -

- Restarting Windows - Restarting Firefox - Restarting Firefox with addons/extensions disabled - 'about:support' > Refresh Firefox - 'about:support' > Clear startup cache - (hamburger) > more tools > task manager > (click the little profile icon for the page playing the video) - I've checked the settings suggested here: https://support.mozilla.org/en-US/kb/fix-common-audio-and-video-issues#w_check-some-firefox-settings

I realise it may be possible to side-step this problem by flailing around with more drastic work-arounds like trying a clean re-install of Windows or a full uninstall and clean of Firefox, but that doesn't really help figure out the problem, which leaves the possibility it could easily happen again to me or others when it might be something that can be more properly fixed or guarded against in Firefox itself, so I hope someone can suggest what might be done to home in on identifying the cause of the problem and so learn whether a more precise fix can be employed.

Hello, I did a lot of search and followed all these advises: https://support.mozilla.org/en-US/questions/1229615 https://winaero.com/remove-your-browser-is-being-managed-by-your-organization-from-firefox/

1. I have not entry "DisableFirefoxAccounts" in "HKEY_CURRENT_USER\Software\Policies\Mozilla\Firefox". 2. I have no policies.json file in firefox directory. 3. I have a message "Your browser is being managed by your organization." in "Settings" (about:preferences). 4. In "about:policies" I have DisableFirefoxAccounts=TRUE. 5. in "about:config" identity.fxaccounts.enabled=false and grayed out.

Please help me to turn on the sync of bookmarks. All these listed issues obviously have something to do with it.

For many years, I have been exchanging video calls on Facebook.

Recent attempts to video call the same person I've been video calling for the past 3 years result in "your browser doesn't support video calls"

Have I been "hacked"?

Please explain.

Could a real person answer this question for me, please? Thank you.

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.

Hello! from this morning and alongside a new Firefox update i've been having graphical artifacts on Youtube/Facebook/Netflix. I've followed all the standard steps.

Disabled Hardware Acceleration. Updated Video Drives. Run FF in Safe Mode without plugins. Disabled Router level VPN and Ghostery.

Any ideas?

I'm running FF135.0 Geforce 572.16 Drives (30th Jan) 3070TI. Windows 10 Pro 22H2.

For about 2 weeks now, the audio volume on youtube videos fluctuates up and down. The volume starts off low when a person starts to talk. For example, when the person in the video starts to talk, their voice volume is very low then within a second or two, the volume rises to normal as they talk. When they finish a sentence and start a new one (when there is a short pause in the audio) their voice is again at a very low volume, rising to normal in a second or two. This repeats as they speak throughout the entire video. This is not specific to any youtube video or youtube channel, it happens on all youtube videos. I have tried updating all audio drivers in Windows 11 - no improvement. I have tried rebooting the computer - no improvement Firefox is up to date, version 133.0 I have tried watching the same videos using Chrome and I do not have this problem.

Yesterday my audio on Firefox worked, today it doesn't. I tried all the regular trouble shooting solutions. - My system volume is not 0 - My tabs aren't muted - My headphones are turned on and working fine (audio works everywhere but Firefox) - I uninstalled and reinstalled my Firefox - I uninstalled and reinstalled my headphone audio drivers - Audio also does not work in a private browser, so I know the issue it's related to extensions, cookies, etc. - I had Windows 11 do a quick diagnostic, so the issue isn't Windows 11 related

Usually when this issue occurs, it's as simple as switching from "default" to a specific speaker in volume mixer, but Firefox is not appearing in volume mixer like it did in the past, as shown in the screenshot below.

I don't know what else to do at this point. In previous documentation here, the solution for some people was to wait and it eventually fixed itself, but I'd rather not have audio for weeks to months on end, so has anyone found another solution by chance?

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:
