In a reply to someone else, I did complain about Chrome's version numbers. That too bothers me. I have to imagine this issue is similar to people who complain about Windows RT's app model. Apple did it from day one, so there are few complaints. Microsoft switched to it just to keep up, which causes a lot of complaints. In this situation, Chrome is Apple who did it from day one without causing a major fuss, and Firefox is Microsoft who switched to it to great fanfare in order to keep up with the competition.
