Putting numbers into context with a browser tool - The Dictionary of Numbers

On May 15th Randall Munroe blogged about an interesting new extension for the Google Chrome web browser called the Dictionary of Numbers:

“It searches the text in your browser for quantities it understands and inserts contextual statements in brackets. It might turn the phrase ‘315 million people’ into ‘315 million people [≈ the population of the United States]’.”

I illustrated it using a grayed version from one of Randall’s Xkcd cartoons that apparently parodied the recent monster movie Pacific Rim. So far I’ve been using Firefox, so I have not tried Dictionary of Numbers yet.
