Hello. I am an anonymous environmentalist with a slight interest in security and privacy. Below is a good start on how to gain some privacy while using the net.
Browse the web with ease and flair: http://seamonkey-project.org/ The Great, Original, Mozilla Browser! Keeping it real. Or, trying to.. Also check out http://palemoon.org/ which is also a very competent browser keeping the user in control. Same project maintains a great email client at http://fossamail.org/
Do so without trackers, viral pushers, and ads: I suggest script blocker: https://noscript.net/ hand in hand with http://github.com/gorhill/ublock a great general-purpose blocker. Comes with a genius point, click, and block feature, a plethora of blocklists, and a very handy DOM inspector for some serious nit picking. Also check out his http://github.com/gorhill/umatrix to get full control over what your browser connects to and not.
Through an encrypted multi layered connection: http://torproject.org/
Speak freely using an open, secure, and free protocol: http://xmpp.org/ Pair it with client to client encryption using OTR: http://www.cypherpunks.ca/otr/ for added security. Also keep an eye out for http://conversations.im/omemo/ which use http://github.com/trevp/axolotl/wiki for encryption.
Slight being the keyword here. For total privacy: download the web and surf offline.
