I tried to like Firefox but any advantages are not worth switching between browsers for personal surfing and work (or incompatible sites). Maybe there is some great plugin I haven't seen that would win me over but as far as security, passwords, etc. I've never felt those should be browser dependent and the 3rd party stuff I use has served me well for years because it is portable and browser independent...and I'm compatable with basically every site I visit by sticking with IE.
Edit: 50 browser wars
