EFF guide to chromebook privacy
@attrc HowTo: Privacy & Security Conscious Browsing
Use the following Chrome Add on's as a minimum
Use a VPN before browsing use
Under Chrome Content settings set plugins to do this:
If you want to get into hardcore mode go to chrome://plugins
Disable adobe flash player
You may find your browsing experience doesn't require flash for daily use.
Use a chromebook and do all the above. Chromebooks work great because users can install extensions only. Executables and such won't run on chromebooks. The risk of malware is low.
I can't stress it enough when it comes to your personal data.
