Simple product (almost everyone wants more or less the same things and/or things are hard to compare, like security) and zero cost of switching is how it happened. It is expected that it would produce this distribution. I've started on Firefox before it was Firefox (2003?), then switched to Chrome when Firefox became slow, then switched back to Firefox when something annoyed me about Chrome (I don't even recall what), then switched to Firefox when I wanted more customization (how do I still live without custom tab colors? sigh), then switched to Chrome again because Firefox started to clamp down on extensions/customization and also it was kinda slow again. As far as I can tell, Firefox is currently in really bad shape... but I would switch instantly if I thought it was better. Google makes the best browser (IMO/so far/for an average user). There only compelling reason for an average user to use a different browser is lack of information.
