Need a different way to filter the Web you use? If you want to block certain types of Web sites, this Firefox extension might be the way to go.
Personal content filter based on user-defined preferences such as keywords, filtering sensitivity settings and URL exceptions. Password protected (default password is “foxfilter”).
Yet another interesting way of filtering content for your Firefox browser. The one feature I really like is the blocking by keyword. That is really neat, and have not seen it in too many other downloads like this.
