There was a great comment i read here yesterday. Developers build stuff on chrome because the console is amazing. So if the user uses chrome, there's a guarantee the website will work.
Yes, firebug started it all, but chrome is killing it right now. Mozilla, why don't you start copying the chrome console already.
What exactly is missing in Firefox DevTools? If anything, they are superior.
I've switched over to Firefox DevTools for 2 reasons:
1. The box model is on the right instead of on the bottom, so I can mess with it and immediately see results in the Inspector styles window and the browser. https://i.imgur.com/KfxmRQT.png
2. I can click on the Event bubble next to the element to see events that are bound to it and go to it if I choose so.
