Electronic Frontier Foundation (EFF) has published a paper on browsers being tracked by it's unique fingerprint. It turns out our browsers are more unique than we would like to think they are so it is possible for websites to track users around using the unique fingerprint. While it may not be possible to know the exact user's identity, tracking from one web location to another is definitely a possibility. User agent sting, system fonts, screen resolutions and much more of the computer attributes all contributes to the unique fingerprint of computer + browser combination.  For those of you really concerned about your privacy, maybe it's time to randomize the timezone settings, fonts and screen resolution frequently (joking). Disabling Javascript and active contents help with this a little bit but you need to decide whether privacy is worth losing the ability to view the active content.

I highly recommend you go to https://panopticlick.eff.org/ and click on the "Test Me" button. My first try said I was unique out of more than 955,000 systems they had tested so far.

For Firefox users, look for the add-on "noscript". It's easy to use and reduced my uniqueness down to 1 out of 950 -- but be sure to go to the options --> whitelist and take out most of what they preload as safe sites.
