WOW... Mint again.  ;-))

What Desktop? X11 or Wayland?

Try downloading Firefox from Mozilla. Download, unzip, and run firefox-bin from the folder and see if you have the same issue. https://www.mozilla.org/en-US/firefox/all/#product-desktop-release

Try your OS or another from a live usb stick and a different desktop.

I seem to be getting kernel updates and NVIDIA updates on a daily basis. I shouldn't be surprised. This version of Mint is only two weeks old. Bound to be a few hiccups not discoverable in a lab. I'll keep this post open for a week or so and see if folks that are way smarter than me can figure this one out. Here is my system info if you are curious.

A kernel update seems to have fixed this issue.

My symptoms were video freezing and resetting within Firefox on multiple sites. After messing about with memory, disk space etc. I found this. As I have been running Mainline Kernels (In Mint: # apt install mainline), I'm usually ahead of everything but I'm also on the Linux Mint edition of Firefox (apparently a very new fork). I upgraded the Kernel to 6.10.10 and everything works great again. Good call!
