If you're browsing the web at work or just somewhere insecure, the prospect of key-logging may keep you from typing passwords and/or expletives. This Greasemonkey-compatible script brings up a virtual keyboard for mouseclick typing.
The Virtual Keyboard Interface is a free script to download and adds one of 22 clickable keyboards for the typing of your deepest, darkest secrets. You just double click any text entry box and the keyboard will pop up automagically in IE, Chrome, Safari or Firefox. Enjoy it, you sad, scary people. [userscripts via LifeHacker]
