If you share a computer with someone else, it can get a little annoying sometimes to coexist peacefully.  I've been sharing a computer for a while now with Wendy, and it wasn't a big deal until about two weeks ago.  I'm a Google nerd, so I'm always logged into their websites for mail and search.  Wendy was always a Yahoo person, so we never really crossed paths.  Worlds collided though when I started up Firefox one day to find that Wendy was logged into Google.  This meant I had to log her out and log myself in so that I could check my Gmail.  This was a major turning point in my life, so I had to do something about it. 

Windows has the option of setting up different profiles, and that seemed to be the solution.  I set up a separate profile for Wendy, but she quickly objected when all the settings and desktop contents were different.  I agree that it was actually more annoying to have to choose a profile to log into when the computer started up.  I previously had it set up to just log into the default profile when it started up.  This added step wasn't too cool. 

The real solution is to set up two different Firefox profiles.  Lifehacker has a guide on how to do this, and it really covers all the bases.  In a nutshell, you have to start Firefox's profile manager, which you can do by going to Start -> Run and typing "firefox -profilemanager".  You have to shut down the current instance of Firefox in order to do this.  From there, you can set up a new profile (I called the new one "Wendy").  Check the box that says "Don't ask at startup".  The key is to make these two profiles easily accessible, so you just need to create a link to each profile.  On the desktop, I made a new link called "Wendy's Firefox" whose target is ["C:Program FilesMozilla Firefoxfirefox.exe" -p Wendy] (without brackets).  The target is case sensitive, so adding a "-p wendy" won't work.  I'm not sure if this is necessary, but to make sure the previously existing Firefox link opens with the default profile, I added "-p default" to the target. 

And voila, Wendy's stuff stays separate from my stuff.  Separate but equal. #technology
