Video stuttering when this extention is enabled.

[Pierelly]

Describe the bug
when firefox extension is enabled video playback, online or offline, stutters severely enough to make me turn it off and go offline without the vpn. even for old black and white shows from the 50's.

I put one into
https://askubuntu.com/questions/1521677/how-do-i-stop-videos-stuttering-when-running-with-nordvpn
with my solution, which is to not use this plugin.
I have notified nordvpn, but as this is a 3rd party extension, not their problem.

apt-cache policy nordvpn
nordvpn:
Installed: 3.18.2
Candidate: 3.18.2

Firefox noscript and an add blocker are installed, but problem remains even when firefox, or mozilla thunderbird, are not running.
or even not online, but with this extension enabled and nordvpn running offline.

my solution was to go offline and stop nordvpn from running (therefore I think the extension problem)
because the nord service wanted to start itself I had to run a loop to kill it.
while true; do sudo killall -9 nordvpnd ; sleep .1; done

problem remained on Wayland or Gnome Classic
problem remained even when choosing to run VLCPlayer in dedicated Graphics chip.
