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 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.

Every time I try to change the resolution of YouTube videos, it only provides 360p as an option, with a "Missing options?" message that redirects me to Google help page that just says my browser might be out of date (I'm on most recent Firefox and Windows 10 updates). The quality is still stuck in 360p when I reboot Firefox in Troubleshooting mode, and there are no quality issues when I use a browser like Edge. What should I be checking to resolve the issue?

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!

When trying to use one particular website on Firefox, I get a message that I am blocked because of an ad blocker but I have not turned on any ad blocker in Firefox. How do I find out if an ad blocker is enabled on my Firefox and, if so, how do I turn it off? I have ensured that the ad blocker option in settings is unchecked and even added this web site to permissions but to no avail. Can someone help? Here is the message I get but none of the steps in this message I am told to take show up on my screen:

Adblock Plus Instructions

   Click the AdBlock Plus icon in the extension bar.
   Beneath “Block ads on”, click the large blue toggle next to “This website”.
   Click refresh.

Were these instructions helpful?

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!

First of all, mods, if I chose the wrong category and this had to go in "customize settings and preferences" feel free to move it :)

So, for several reasons I decided to completely disable SSL and the old TLS 1.0 and 1.1. I still didn't decide if TLS 1.2 is still important or it's enough with 1.3 so for now I am leaving them both. I did this system wide, with PowerShell, following the instructions in THIS THIS article.

But then there's Firefox. I don't know if Firefox can establish SSL (or old TLS) connections despite the system "ban". But I came across THIS THIS article about how to enable TLS 1.3 in Firefox and when I went in about:config and I typed "security" I saw that there are a lot of voices with SSL and a lot more about TLS than just the security.tls.version.max mentioned in that article, so I am here to ask you what to do to be 1000% sure that all SSL and older TLS are completely disabled in Firefox, and that only TLS 1.3 is enabled.

If you have reasons to believe that disabling TLS 1.2 is not a good idea, let me know, but in THIS THIS article I've read that 1.3 is much better and it's anyway backwards compatible with 1.2 in case some server only supports 1.2, so I decided to leave only 1.3.

Thanks!

I have a PC. Today, Bing took over my Firefox. I have to go through Bing to get Firefox. I don't want that. I just want to use Firefox.

Note that I use two web browsers. Google Chrome (default) and Mozilla Firefox. No others. I don't want Bing.

I purged Bing from Chrome by making Chrome my default, which it has been. I use Firefox some of the time. I don't want to get to Firefox by going through Bing. Microsoft has enough domination.

I want to turn off the hover preview feature. First I went in settings, but that disabled only the thumbnail (browser.tabs.hoverPreview.showThumbnails in about:config is set to false and saved). Then I went in about:config and manually set browser.tabs.hoverPreview.enabled to false as well, that disables the unwanted feature completely.

But every time I restart the browser it's turned back to true (just hover.Preview.enabled, not hover.Preview.showThumbnails). Can I save my settings? It's annoying that I can't opt out.

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.
