Hopeful solution. Minor Problems. Rated 4 out of 5 stars

This add-on has a sufficient list of features to protect kids from adult material. However, I found several important problems:

1. Word Censoring mode briefly shows you the unaltered web page, complete with bad words, then
it will quickly asterisk out the bad words.
This part doesn't work that seamless.

2. Word Censoring mode seems to not work at all in frames!

3. Explicit Material Filtering seems to catch legit pages. Pages get blocked and asks you for the password. However, ProCon doesn't have a way to inform you as to which bad word caused the block to happen. Hard to iron figure out which bad word was the offending word.

This review is for a previous version of the add-on (1.6).
