Firefox Tekoha Aty

The same thing happens on my two Dell laptops (Inspiron and Latitude), and a Hyper-V VM (on my desktop PC). They all run Bazzite Linux 6.17.7-ba25.fc43.x86_64.

A video may play for a second or two, and then it's either a black screen, or an error message of "The content doesn't seem to be working."

On the same two laptops and VM, the Chromium Browser, and LibreWolf (a fork of Firefox?), have no issues playing the same videos.

Firefox version on all three systems is 147.0.3.

Any help/guidance welcome with thanks.

I am running Firefox 147 on a Windows 10 desktop PC. I am using DualSafe Password Manager. However, the 'Ask to save passwords' option is ticked in my Settings (see attached screenshot), and also greyed out so I can't alter it. Firefox keeps asking to save passwords for sites that I sign into. Can anyone suggest how I can fix this. To my way of thinking, if a thrid-party password manager is installed, Firefox should see this (it does) and automatically set itself to not ask.

4 rows of links working great and sync killed it all. Data is in the prefs.js file but firefox wont read it how can I fix this? Hours I have been chasing around with ai checking all the settings etc. wth? HOW HARD DOES THIS HAVE TO BE? please help before I uninstall and never come back. Wasted way too much time!
