There are some sites that you know you spend too much time on - not DownloadSquad, of course. And certainly not the Time Wasters tag page.

Other places like Facebook, Twitter, and dental hygenist web sites can turn into real time sinks if you're not paying attention. If you need a little outside assistance in breaking free, get your hands on the NoAddict userscript for Greasemonkey.

Adding domains is simple - just clicking in to Greasemonkey's manage scripts window modify the script's source using your favorite text editor. The code is straightforward: // @include https://website.toadd.com/*.

Yes, with a little self control you can accomplish this without the need for any software at all, but sometimes a little shove in the right direction is necessary.
