Browsers handing colors differently

Ive heard before that different browsers (IE, Firefox, Safari) handle things such as coding differently, one webpage may look right in Firefox, but not in safari. But Ive never heard of them handling colors differently. Take a look at this shot, Im noticing a huge color shift in this shot.

But Im not noticing it as much in this shot (its still there, just not as painfully obvious.)

There is a huge difference in the first one right? Its not just my screen? Why is it doing this? They are all in the same color mode - 8 bit/chanel and RGB.
