The Firefox UI on Ubuntu 20.04 was very slow for some reason. But this trick was a good way to help speed it back up.
Go into about:config and then set the value below to true and then restart the browser.

This seems to have sped it up greatly. I am not sure why this is. Firefox is very fast on Windows, but this does feel faster, even running an intensive ffmpeg command in the background, it still feels much more responsive.
Thank you worked great
