Substitutions per ollidamra

A simple addon. When enabled, it applies various replacements to all webpages to make them more amusing. It can be enabled and disabled through your about:addons page.

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.
