From Tim Lauer comes a link to this Greasemonkey script for Firefox that will turn any bad words you choose into asterisks if they try to load on the page you are viewing. Tim says:
Clean Language is a Greasemonkey script that filters out selected text from a web page before it loads in your browser. You can set it up to remove the offending words, or just replace the word with some other nonsense characters. The script comes with a preloaded list of offending words and can be edited to include any words you like. I’ve played around a bit with it and it works well. So if students were using the Firefox browser with this script loaded, then you would be able to filter offending words not only from Wikipedia sites, but any page that was visited when using Firefox. Am thinking I’ll load this script on our next lab image.
First of all, I always do what Tim’s doing because he is without question the most Education 2.0 principal in the land. Hands down. Second, if I can make this work, and I just did, so can you. What I like about this is that I can control it. I’ve chosen not to block some of the preloaded words on my home computer and added a couple of others. My choice.
