Coprolalia is involuntary swearing or the involuntary utterance of obscene words or socially inappropriate and derogatory remarks. (From Wikipedia)
After you install coprolalia it will bluntly insert swearwords into the text of the web pages you visit. No clicking or anything required. Works only on English web pages.
You can turn coprolalia on and off quickly by clicking the smiley icon in your browser's status bar.
