I just checked if browsers on Fedora and on Ubuntu use x11 or wayland using xwininfo. Firefox uses Wayland while Brave and Vivaldi use X11.  
I read Madaidan’s Insecurities and he states that Chromium browsers have better security than Firefox browsers on Linux. Ok.  
So which is more secure then? Using a chromium browser with X11 or using Firefox with wayland?  
This is really confusing.

Chromium. Its quite easy to switch Chromium to Wayland: [Chromium - ArchWiki](https://wiki.archlinux.org/title/Chromium#Native_Wayland_support)
