I don’t know I’ve used a lot of browsers in my life from the old Netscape and everything in between; Opera, Konquerer, Firefox, IE, Edge, Chrome etc.
I think Chrome shows that if you build a better browser then people will use it. I use Chrome now because it just works, I used to use Firefox for the same reason. Plus, I will say that Chrome has done more to remove the stranglehold that IE held over certain parts of the web.
I will one day try Firefox again and if it works better than Chrome then I will be likely to switch.
