Avoid distraction on the internet!

I have just found this add-on for Firefox called Leechblock.

It allows you to block certain websites on your browser. I have added a number to it already - sites which are addictive and a complete waste of time. I have tried just using willpower before, but...

What you can do:

• Block certain sites all the time.
• Block sites only at certain times (e.g. when you're supposed to be working).
• Allow yourself a limited daily dose (e.g 10 mins only).
• Set a temporary block if you want (e.g. not allowed in for 4 hours.)
• Set a password (though some reviews say it's easy to get around, so not ideal for strict parental control) but you don't need to, and can just use it as a tool for self-discipline.
• Sort your sites into different groups with different rules.
• Block all internet access except x. This could be useful when the only reason I need to connect to the internet is to listen to the radio or podcasts.

Wht it doesn't do: block all access to the internet except that which is genuinely work-related. I suppose mind-reading hasn't come that far yet.
