I use Chrome because of its built in password manager. Every time I set up a day to move some of those passwords somewhere else I feel I have something more "important" to do. I used to use Firefox a lot, but at one point it has so many performance issues, it was unusable for me and Chrome was like a breath of fresh air. I have Firefox installed now, and sometimes browse with it, but I get the feeling that websites look odd in that browser, as if I was not seeing the websites as if they supposed to look.
