Browser Development • Re: Linux Pale Moon with Qt toolkit

main reason was the lack of security with X11 since it's apparently insecure

X11 has been secure for decades. But ask a Wayland proponent and they will say it's insecure, because they want to marry system core tasks with a graphical environment in Wayland. Not sure who you've been listening to but that very premise makes Wayland actually less secure when looking at the real world where bugs exist.
