There is always libreoffice

Do you know of any resources about this, and/or how to implement it?

My theory to why they don’t allow firefox or linux is that due to the freedom of both of them. This makes it so you can stop the website from knowing that you are not focused on the tab/window, and you can stop the website from locking fullscreen.

It is possible to make the website think I am using chrome and windows, but I don’t want to get in trouble for cheating. Even if I use degoogle Chromium it still won’t allow me because I use Linux.
