Opera is one of those browsers that stores your cache on their servers to make your browsing quicker.Your browsing habits are already going through their servers.Now add Facebook to the mix.What do you have? The mother of all profiling softwares.☼

Only if you enable Opera Turbo (http://www.opera.com/browser/turbo/), which came disabled by default on my installation.
