Been using it since it was Netscape Navigator. It's the only solution for me, that has stuck. It's not like I haven't tried anything else like Opera, Waterfox, Vivaldi and a few others. I have never installed Chrome though... Firefox is the only one I feel safe with... A few addons, and a few tweaks, and like you, I'm good to go...
I can see that people really have a hard time when someone speaks figuratively...
