A simple extension. When enabled, it applies various replacements to all web pages to make them more amusing. It's only settings are to be enabled or disabled. Originally this was based on the xkcd comics #1288, #1625, and #1679, but now it does much more. In addition to applying most of the xkcd substitutions, it aso does a few of my own. Beyond substitutions, the addon does a number of other things sporadically. It will sometimes replace images, make the text zalgo, change the font to comic sans, change the font color, or for longer text nodes, replace the text with an excerpt from "The Cat in the Hat" translated to russian. Overall, this addon should make the news very amusing.
