Every time I tried o watch a video in Firefox, any website, I get the error "There was an error loading or playing the video". But when I try using Chrome, everything works just fine. What do I have to do?

Do you have FFmpeg and perhaps libavcodec packages installed?

Patent and copyright restrictions are among reasons why many Linux distros do not come with packages such as FFmpeg in a new install as it provides codecs needed to fully support HTML5 players.

As you using a flavour of Ubuntu so perhaps see https://linuxconfig.org/ubuntu-20-04-ffmpeg-installation or https://help.ubuntu.com/community/RestrictedFormats

Chrome/Chromium basically cheats by coming with its own codecs.
