I started using Firefox because of Firebug when it first came out. It made web development so much easier. I continued to use firebug until it was discontinued (I still feel that it was superior to the dev tools built into the browsers, at least as they were at the time it was discontinued - I remember the console was especially better). I’ve continued to use Firefox since then out of years of habit.
