Whenever I open Firefox it doesn't open as a maximized window, just a rectangle. At first I didn't care but after some use it's been getting annoying and now I'm trying to fix it. I tried following this guide but to no avail.
(Ubuntu 18.04.3 LTS - Firefox 69.0 64-bit)
R-Kiosk
extension and the-fullscreen
argument: https://askubuntu.com/questions/36287/how-to-start-firefox-in-fullscreen-mode - BTW I'm not sure that this is the correct link, it's something about a corrupt xul. – Yaron Sep 23 '19 at 06:14
