Easter eggs in your favorite services and products are awesome to discover, aren’t they? Here are three of them hidden in Firefox.

2. Run Firefox within Firefox: Paste chrome://browser/content/browser.xul in Firefox and hit Enter. You’ll see a second instance of Firefox open up right there within the first. You can open up a third one similarly, but you can’t go beyond that.
