1. Ghostery 2.4.2 by David Cancel, Felix Shnir
Ghostery sees the “invisible” web, detecting trackers, web bugs, pixels, and beacons placed on web pages by ad networks, behavioral data providers, web publishers, and other companies interested in your activity.
Ghostery allows you to block scripts from companies that you don’t trust, delete local shared objects, and even block images and iframes.
Ghostery also includes the optional, opt-in feature called GhostRank, which sends Ghostery servers anonymous information about the trackers you encounter and where you encounter them. This allows us to create a more comprehensive list of detectable items, and helps us create a more transparent behavioral advertising ecosystem through our partnership with Better Advertising.
PROTECT YOUR PRIVACY
Ghostery is built and maintained for users that care about their online privacy, and is engineered with privacy as a primary goal. Ghostery use is anonymous.

Neither the Ghostery application nor Better Advertising receives any data from Ghostery users unless the user opts-in to participate in GhostRank. GhostRank data itslef is anonymous, is NEVER used for advertising targeting purposes, and is only shared in aggregated, non-personal, statistical form.
2. Torbutton 1.2.5 by Mike Perry
Torbutton provides a button to easily enable or disable the browser’s use of Tor. Torbutton provides enhanced privacy and browser state isolation features that make it more private and secure for Tor usage than any other general purpose proxy switching addon. It can also be combined with multi-proxy switching addons to provide Tor protection when the Tor proxy is selected, but please see the FAQ for important security information about filter-based addons such as FoxyProxy.
It can also be used independent of Tor for general privacy management with an auxiliary proxy such as privoxy or polipo.
