Web Site Filter
A content filter for websites.
It has a number of key words, which it tries to find on the web page. For each word found, a score is incremented. If a certain limit is passed, the page is blocked with a very simple message.
Web Site Filter: A Content Filter for Websites
Web Site Filter is a Firefox add-on that provides content filtering capabilities for websites. It uses trigger words and a scoring system to determine if a page should be blocked. Combining it with other blockers can enhance its blocking capabilities.

Add-on summary
The trigger words are a regular expression that was taken as-is from the (GPL-licensed) DansGuardian.
If you also need to hard-block certain words or URLs -- block every page where they appear --, consider combining this filter with word/url-based blockers such as ProCon Latte. Or also have a look at Fox Web Security which blocks based on hostnames, relying on services like OpenDNS, Comodo, Yandex.DNS and Norton.
This add-on can augment the above by its score-based filter.

It works well, the points system is interesting, it doesn't keep blocking all sites madly. But it has some annoying problems, sometimes it starts blocking any website, then you have to uninstall and install again; the extension has for some reason quotes and commas set to block, so if a page has that, the extension will score and maybe block the page (And I didn't find where they are, so I don't know how to solve it.)
