See No Evil 5.0 - Automatic Word Censor
SEE NO EVIL automatically replaces objectionable words with various "clean" words and phrases in ANY websites you select. Works extremely well with YOUTUBE. Replaced words appear in red (optional) or not at all(optional). Also offers a feature that allows YOU to select words to be replaced and their new replacement. If desired, you can simply have all objectionable words removed and not replaced with anything. Includes a "one-time" feature that allows you to temporarily replace words on any website you are viewing at that time. Additionally, you may block ALL comments from specific YouTube users if you keep running up on the same person using profane language.
