When was the last time you were in control of your Internet? Well, you can now be with BlockSite addon for Firefox. Blocksite is an extension, which automagically blocks websites of your choice. Additionally, this extension will disable all hyperlinks to these websites, by just displaying the link text without the clicking functionality.
While not a great security tool or a feature rich utility, it is certainly a lightweight user plugin to simply block websites you do not want to access. This addon works on Firefox 2.x and lets hope there is a version for 3.x comes out in time when Firefox 3 releases.
