Back in ancient times when I used Windows, I had a couple of application icons in the system tray thing; one was called Nada which did exactly what its name suggests, and another was Dr. Windows which would just show a popup "Dr. Windows is working" and otherwise did the same as Nada.

Yes, I use Firefox everywhere too. Or Librewolf.

Then again most people do not even know anything about their computer as they only use a browser, hence why chromebooks are a big hit.

Another reason to use firefox. I personally run Firefox beta on all of my mobile devices.
