Firefox will not play video on Linux

Firefox 129.0.2 (64-bit) Mozilla Firefox Snap for Ubuntu canonical-002 - 1.0 Running on kubuntu Linux 24.04, kernel version 6.8.0-41-generic (64-bit) KDE Plasma Versio… (閱讀更多)

Firefox 129.0.2 (64-bit) Mozilla Firefox Snap for Ubuntu canonical-002 - 1.0

Running on kubuntu Linux 24.04, kernel version 6.8.0-41-generic (64-bit) KDE Plasma Version 5.27.11 Qt Version 5.15.13

I've posted a description of my problem on the kubuntu forums: https://www.kubuntuforums.net/forum/newbie-support/help-the-new-guy/681835-firefox-eating-up-a-lot-of-cpu

Here is a synopsis of my posts on that thread to distill the most noteworthy symptoms:

I have snap Firefox installed.

$ snap list Name Version Rev Tracking Publisher Notes bare 1.0 5 latest/stable canonical✓ base core22 20240731 1564 latest/stable canonical✓ base firefox 129.0.2-1 4793 latest/stable mozilla✓ - firmware-updater 0+git.5007558 127 latest/stable/… canonical✓ - gnome-42-2204 0+git.510a601 176 latest/stable/… canonical✓ - gtk-common-themes 0.1-81-g442e511 1535 latest/stable/… canonical✓ - snapd 2.63 21759 latest/stable canonical✓ snapd thunderbird 128.1.0esr-1 507 latest/stable/… canonical✓ - $

If I start firefox from the shell command line, it runs fine. It runs the shell script in /usr/bin/firefox, which ultimately executes /snap/bin/firefox. Clearly that shell script is doing some configuration that I don't understand.

If I​ hit Alt-space I see the menu in the referenced screen grab (see attached).

If I select the first entry, to run firefox from the command line, it has the same effect as starting /usr/bin/firefox from a bash shell; it works fine. However, if I select the third entry, firefox does not play any video; I've mostly tested with YouTube videos that have actual video and audio.

I'm not sure what gets executed when I select the third option from the Alt-space menu. It appears from doing a "ps -ef" that it's the same /snap/firefox/... executable. But I'm wondering why is this entry in the Alt-space menu and how does it get initialized or 'configured' to run.

Additionally, if I do start firefox from the entry with the firefox browser icon, and it fails to play video, I must then uninstall firefox using snap and then reinstall in order to get video playback to work. That is, after a failed start, simply exiting firefox and restarting it from the shell command line will not work; firefox will not play video correctly at all.

I also noticed that on my PC desktop, "snap list" lists firefox as "firefox 129.0.2-1 4793 latest/stable mozilla✓ -"

But on my old Lenova laptop running the same kubuntu version, "snap list" lists firefox as "firefox 129.0.2-1 4757 latest/stable mozilla✓ -"

​I'm up to date on both systems via "sudo apt update"' and "sudo apt upgrade"

Even more frustrating, today, for the first time, despite starting firefox from the command line, video still didn't play. I had to uninstall firefox and reinstall it.

Today, Firefox stopped playing audio on Facebook videos and won't play Netflix videos at all (Netflix error code: F7701-1003). Youtube works fine and has audio, but several other video sites I've tried have video but no audio. It was all working fine yesterday and I haven't changed any settings.

These websites work fine with both audio and sound on Microsoft Edge on the same laptop, so this is a problem exclusive to Firefox. OS is Windows 11 Home 23H2, Firefox is latest version (129.0.2)

Things I've tried: 1. Refresh Firefox settings 2. Download and install fresh copy of Firefox 3. Toggle DRM content in setting on/off - no difference no matter what is selected 4. Ensure that 'remember history' is selected 5. Check for Windows updates 6. Uninstall audio driver, restart and fresh install of audio driver 7. Ensure it's not in private mode 8. Turn off all extensions 9. Check volume mixer allows sound for Firefox 10. Clear the cache and cookies

I can't find any more suggestions on the internet, so any further suggestions welcome!

Hey guys,

Can you please tell me how to get my extensions to appear on the toolbar? As you can see from the image (titled "forFirefox03"), only one is shown.

The images (titled "forFirefox01" and "forFirefox02") show all the extensions that I would like to have on the toolbar.

I've included the "About Firefox" (titled "forFirefox04") to show you which browser version I have.

I don't know if I need to show you the title names, but I'm used to Microsoft Answers, where I can put the images between the text, and here, I can't, so I'm assuming I have to show you them as names and images.

How to Restore Favicons Lost for All Bookmarks in FF 129.0.2 (64-bit)

On two occasions all of the favicons for my Bookmarks have disappeared. The only way I have been able to restore them is to open each bookmark using "Open All in Tabs" for each Bookmark folder. As I have many hundreds of Bookmarks, this is an extremely time consuming process. I have done this twice. I have just encountered a third instance of this problem and would like to avoid doing it again if there is any other way to restore the favicons.

I had saved the favicons.sqlite files from the Profile, but I am unaware of any way to restore the favicons directly from this file. The favicons.sqlite file appears to be of the proper size, i.e. ~17KB. On the last occasion, following a suggested solution, I rebuilt the iconcache hoping it would also rebuild the favicons, but that was not the case. As a result, I used the above process.

Any solutions to restore the Bookmark favicons without opening all with "Open All in Tabs" would be greatly apprecuated. I don't know what has caused the favicons to disappear. I am running Firefox 129.0.2 on a Windows 11 Pro PC.

I just installed an update when prompted by Firefox. Now I can't log into Hotmail.

FF 129.0.2 x64. The update restarted FF. Everything else seems to work OK. But when I go to Hotmail.com, at first it displays my Hotmail inbox - which is odd; all other webpages requiring a login were logged out when I installed the update, requiring me to log in again - but then it switches to an error:

Something went wrong and we can't sign you in right now. Please try again later.

The Microsoft account login server has detected too many repeated authentication attempts. Please wait a moment and try again.

The same Hotmail account is still logged in and functioning on Chrome. This is why I think it's a FF-specific problem.

I run Firefox on a Mac. I've saved my gmail login credentials in my Firefox saved passwords. About a month ago I started having a problem where opening the gmail login page no longer autofills my gmail username. I've used Firefox, Gmail, and Mac together for 14 years. This has never been a problem until July 2024.

I can't find an answer in Mozilla Support, Stackoverflow, etc.

I recently explored the backgrounds on Firefox. I choose one of the, because they look really nice. But after I changed my Firefox Data Collection and Use settings the background disappeared.

Why do you have to keep "Allow Firefox to send technical and interaction data to Mozilla" and "Allow Firefox to install and run studies" enabled?

Hi there, after turning on my computer in the morning, Firefox has been suddenly rendered utterly inoperable and pulls up a PR_CONNECT_RESET_ERROR for all websites. No matter what I do, including all other fixes previously suggested on the Mozilla forums and elsewhere, nothing seems to work.

Things that I've already tried and did not work include: - Pausing Kaspersky Internet Security - Resetting WiFi router - Switching to a different WiFi - Turning on troubleshooting mode - Resetting Firefox entirely - Creating a new profile - Reinstalling Firefox (several times) - Installing Firefox for Developers - Flushing DNS - Turning off proxy settings

I really don't want to be forced to use Google Chrome. Is there anything else that I can possibly do that can fix this?

Hi, out of nowhere my Firefox has stopped loading any pages for the past hour. I have read the existing community articles and cleared all of my history, cache, cookies, and restarted my computer 4 times. Firefox is up to date and was working fine up until I left my computer and returned to it an hour ago. I haven't downloaded anything new or clicked anything weird, I was just listening to a regular podcast this morning. All websites either show up as left-aligned text with no images, or are completely blank. This includes Gmail, Tumblr, Youtube, EyeBuyDirect, etc. All of these sites load perfectly in Edge so the issue is specific to Firefox. Any help is greatly appreciated.

Edit to Update: I turned off my AdBlock extensions one by one to narrow down the issue. The problem was AdBlocker Ultimate. I disabled it and now all my websites in Firefox are working as normal.

Hi there! My linux crashed and I only have an access to the terminal now. I'm trying to save login information and bookmarks that were saved in the browser. I didn't use an account. So I'm trying to find a location in the linux system where it was saved. I used 'find' command with key words 'mozilla' and 'firefox' to find possible locations but I'm not sure that I covered everything. Maybe someone here knows exactly where I should look. Thank you for you help and advance :)

After my Windows 10 laptop being in sleep mode I found my background picture changed and all my Firefox tabs missing (while my bookmarks, add-ons, history etc. saved, and all other apps functioning properly). Recently Closed Windows menu was inactive and using Restore option in Library had no effect (despite availability of recent saves).

I found out that Mozilla folder was just missing in %appdata% (e.g. Profile Folder in about:support leaded to a non-existent directory). No manual changes to Firefox settings/data were made and no new profiles created.

What might be the problem and are there any ways to restore my tabs?
