Microsoft Edge is now more popular than Firefox on desktop

It happens to be a nice browser. I still prefer Chrome
I also usually switch to Secure Browser when doing banking, shopping etc.
Browsers and which one is best have always been a hotly debated topic.
Somethings in life never seem to change. 
Personally I see no difference in this to the Internet Explorer, captive audience with the browser installed with your OS.
I still prefer Firefox, different strokes for different folks
