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.

I want to create a list of allowed web sites in settings/cookies&data/manage exceptions, but it seems I have to enter each site MANUALLY. I would like to do this more quickly and easily by just selecting sites in the "manage cookies" list and designating them as exceptions. Or is there already some other way to do this that I haven't found? Also, after I have made exceptions for all my important sites, by whatever means, can I assume that I can press "delete all" in the "manage cookies" list and the allowed sites will not have cookies removed? What happens to exceptions if I select "delete cookies and site data when Firefox is closed?" If there is no way to make exceptions other than manually, I respectively request that some convenient method be added to the program. Thanks for any response.

Whenever I hover on a tab, a small pop-up immediately appears with the name of the tab and its website address. Sometimes this box is above the tab (and extending above the top edge of the window) and sometimes below it. This behavior started recently with no action on my part. How can I stop this annoyance?

For some reason I cannot type anything in Google Docs on the Firefox Desktop Browser. In fact, it seems like the browser doesn't recognize that I'm using Google Docs at all - in my attempts to see what was up I tried to bold a word to see what would happen, but the Ctrl + B shortcut opened the Firefox bookmarks tab instead. This is happening across all my Google Accounts, but only on Firefox and only in Docs - I can edit sheets and forms without issue, I can edit them all on my Android through the google apps, and I can edit them in another browser.

This is an issue that happened suddenly yesterday and I cannot think of anything that's caused it. I double checked that I had editing permissions on these docs, asked the people who owned them to remove me and re-add me but no luck. I have cleared cache and cookies, logged out and back, restarted the browser, and restarted my computer. Though I haven't changed anything with my extensions recently, I tried deactivating and reactivating everything I had. None of this caused any difference and I still cannot edit. I've also tried a user-agent switcher to see if that could help, but no dice. It really does seem like the issue is firefox not recognizing Google Docs is Google Docs and I'm not sure what the fix for that would be. Any advice would be greatly appreciated.

Hi, A few weeks ago, I wanted to sync my open Firefox tabs between my old laptop and my new one. I signed in to my Mozilla account on both computers, and the sync process worked just fine. For weeks, my synced tabs appeared in my Firefox sidebar on my new laptop, and all was good. However, the other day, I had to restart my computer a few times, and when I open Firefox again, my synced tabs were gone. On my Mozilla account page, it still says that I am signed in to my old laptop. How can I see my synced tabs again? Thank you very much for your help!

I have dealt with this tiny font problem before but did not retain the fix because I actually thought I had solved the problem once and for all.

BUT, I wake up this morning, having made no changes to this laptop overnight, only to discover that the fonts on my Firefox browser controls are tiny tiny tiny.

I expect Firefox/Mozilla to resolve this LONG-STANDING problem once and for all. I have made no changes to this browser in the last 24 hours. There were two MS updates that occurred overnight, but I doubt this affected the fonts on the Firefox application.

If there is a straightforward FF/Mozilla doc that addresses this problem (since it is recurring and well documented by others over the years), I would appreciate a link to this document. And if there is a known problem with certain MS updates I would appreciate knowing about this as well.

TIA

The same website Chrome is correctly operating.

Since the recent update to Firefox 131, I can no longer use the Billpay option of my TD Bank account. I am able to log into my account without any problems and use all of the options except for Billpay. I want to add that I know I am not alone with this problem as I have seen several others with the same problem but with different banks. It is the Billpay option which no longer works.

As I said, the bank site is fine until I click on "Billpay", Then I get this: begin quote: "Why can't I access Bill Pay?
