I don't know if people know my history but I used to recommend Privoxy. Because of the current situation I switched to recommending NoScript, at least for Windows machines. Imagine my surprise when I found out that a SysAdmin for a Math department at a major University in the United States mandated Firefox and NoScript for everybody for security and administrative reasons. They have less than 3-4 Windows machines, several dozen Sun Solaris boxes, 30-50 Linux boxes and the rest are all Macintosh OS-X. NoScript on Unix! It gives you pause to think that is how bad it is getting now. A lof of department members are complaining but the SysAdmin staff are holding firm. I have NoScript on Windows but not on Linux or OpenBSD.
Another one you may want if you don't have it yet and use Firefox is BetterPrivacy:
https://addons.mozilla.org/en-US/firefox/addon/6623It has removed hundreds of flash cookies (LSOs - Locally Shared Objects) for me. Most are harmless but there are hosts that have entered my hosts lists based on the content of their flash cookies. I wouldn't dream of going without BetterPrivacy installed in Firefox.
