Simple Content Filtering

It would be great to allow a parent to specify a custom list of adult content keywords that would help block any adult content. If a blocked keyword is detected anywhere in the HTML document, a "Page blocked due to content filter preferences." message would appear instead of the HTML.

If Mozilla could help manage a list of "typical" adult keywords that could be downloaded to the client when an update is detected, that would be even better (similar to NAV virus updates). The user's custom list of keywords would remain unaffected.

The trick would be to allow for multiple keywords and phrases such as:

"xxx", "porn", "free AND adult", "free AND sex", etc.
