Did you realize that Flash is tracking you? That’s right, even if you clear out your Firefox cookies on a regular basis, Flash is storing loads of secret hidden cookies that track you. Unless you install BetterPrivacy, that is. It lets you auto-delete them.
BetterPrivacy
Did you realize that the DNS cache on your computer is tracking everything you do, even if you use Google Chrome’s "Private Browsing" mode? Simply use this command line to view everything in the cache:
ipconfig /displaydns
Then use this one to flush it:
ipconfig /flushdns
This thing is completely driven by hotkeys – use Ctrl+Alt+Z to hide the windows, Ctrl+Alt+L to hide the dialog, and double-click the readme file to figure out all of the others. It’s tiny, useful, and works really well.

The TrackMeNot extension for Firefox 3.5 offers an additional layer of privacy for the surfer. By periodically sending random search queries, TrackMeNot increases the difficulty of search data indentifying individual users. Another great tool to protect your online identity.
Install TrackMeNot v 0.6.2a on TMN’s homepage
Install TrackMeNot v 0.6.29 from Firefox Add-ons
The coders of Spyware Blaster wrote a lesser known app that is quite handy. EULAlyzer scans End User License Agreements for keywords that might compromise your privacy or security. A pro version runs in real time.

We do enjoy sharing Firefox addons that extend a users privacy. BetterPrivacy protects against super cookies, “undeletable longterm cookies”. This extension has a few options that you can enable including deletion of these super cookies at Firefox startup, shutdown and by automatic timer. So far this addon has deleted 2563 super cookies for us since early 2009.
