Some of these rules are oddly contradictory.

> 4.2. Do not use unofficial Firefox plugins.

Ok, fine.

> 4.13. Install an ad blocker if available. Firefox does not have an ad-blocker built in. Most people use Ad Block Plus, which is a Firefox extension.

Instructions unclear.

EDIT: This one made me laugh:

> 3.4. Turn off your home Wifi router at night and when you are not at home. At night, or whenever you are not at home, there is no need for your router to be powered up. Having it on means that someone can theoretically hack into the router itself from anywhere on the planet.

Leaving it on while I'm home and awake will keep me safe though.
