This is how I encrypted my web browsing.

Windows:

1) Download Putty from Columbia (or anywhere, it's free.)

2) Follow this guide

3) Paraphrasing from the above guide (which has helpful pictures), you set up Putty to connect to Cunix (Columbia's SSH server) and establish a tunnel along a certain port. The guide above uses 5150, but it can be any number between 1025 and 65535. You should come up with your own. We'll call it X.

4) You log into Columbia's SSH server using your Uni and password. Once you are connected, the tunnel is active. Leave that window open.

5) In Firefox: Options-->Advanced-->Network-->Settings. Select Manual Proxy configuration. Enter localhost in the line titled "SOCKS proxy." Change the port to X. Select SOCKS v5. Hit OK and you are done.

You can search around for what to do for Mac and Linux systems. Obviously, anytime you want to use the tunnel, you will have to open Putty and log onto Cunix. I think it's simple enough like this, but there's probably an easier way too.

I use the following Firefox extensions: NoScript? Ghostery Better Privacy

I also keep the default setting under Options to accept no cookies, and only make individual exceptions (under "Exceptions") for sites that won't work without them, and for those, I make the exception to allow a cookie for the session only. It's actually not that much work, beyond adding any necessary exceptions once.

NoScript? also requires some attention to allowing certain javascripts without which certain sites won't function, but the protection from malware is worth it, and it also blocks privacy-related stuff as well.

Ghostery and Better Privacy need little to no attention, they just work in the background to block various pernicious tracking devices.

Also, for Thunderbird users, there is an add-on called Enigmail which is an easy way to add PGP capability to your Thunderbird client.
