One more thing. On my main browser, I run an extension called Domain Whitelist. So, instead of blacklisting certain sites, you have to whitelist them. It works pretty well. But one thing you learn is just what an INSANE number of sites you're accessing when you access a regular webpage. For instance, you can't just whitelist gmail.com, there's dozens if not hundreds of accessory sites that are also used, and need to be white listed.
