I don't have any problems with firefox at all, it tracks me across three or four different computers
if using the fox, try deleting your cookie database, and/or playing with the "delete all cookies on exit" or something?
if using internet exploder, then shame on you! I note from my site stats that nearly two thirds of OESFers must be using 'fox as they form the most clicks on my site - take a look:

p.s. more of you should be running linux on the desktop - shame on you; may I humbly suggest if you really need windows, use a small vmware machine with the free vmware player.
