Firefox was my default browser for 3-4 years, but with Chrome speed propouse I started my browser chage. And after some terrible discover that Chrome have a "spyware" style for sending information evean i'ts not have a page open, or its google update installed aas service, startup application, task schedule and I not sure if there's some place more... I abandon both, and use IE9. Be honests IE9 is faster than Chrome and Firefox; and better: do not have a Chrome "spyware" style.
