I use 3 browsers, IE as my main account for normal stuff and I don't clear cookies that much so I can always be logged into my favorite sites plus can check adsense, affiliate networks etc. I have always used FF as my browser when I wanted to do anything that I did not want to be connected with me. Lately I started using chrome just to have an extra option for logins and making gmail, yt, yahoo accounts etc. But yeah I guess I need to be careful with chrome, even cleaning it before I use it I'm sure Google has it;s dirty fingers sniffing around some how with it.
