You can set CookieCop2 to automatically reject all cookies and then specify each time you go to a site where you want the cookies that you want to allow them (some sites are not accessible at all without cookies). It also allows you to remove cookies for sites you have not allowed.
It also allows you to block sites completely, and to ask before opening a popup (but misses some still). It can scan js
for cookies and maintain a DNS
This lowers my cookie number down to the 150 or so that I want to keep. http://www.pcmag.com/article2/0,4149,3346,00.asp
