Using add-ons in Firefox to enhance your experience is boring. For April Fools' Day, lets make the experience a little more bizarre.

Since these add-ons were meant to be installed on a victim's computer you'll only need two things:

- a victim who uses Firefox as his or her regular browser
- access to the victim's computer

To keep it simple, here are the links to all of the add-ons for your one-stop shopping pleasure. Each step will explain what each of these does.Just click on a link to install it in Firefox.

- Two Steps Back
- Rick Rollr
(Video removed by YouTube)
- The Devil's Inbox

Step 1: Two Steps Back

Once in a while the browser will go two links back instead of the next link forward. This is pretty subtle and will definitely frustrate someone and make them think they're going crazy. We recommend that you let them in on the joke before too long.

Step 2: Rick Rollr

Getting people to click on links that sends them to the Rick Roll video is hard. They're on to your silly ways, but what if there was a 2% chance that any link, on any page, would Rick Roll them? Yeah, it would drive 'em nuts.

Code:
if(Math.random() > 0.98){
   window.location.href = "http://www.google.com";
}

That's a 2% chance of your window being sent to the google page. Tweak the number between 0 and 1 for odds of it happening and the URL for the target video.

Step 3: The Devil's Inbox

If your victim uses Gmail, then get ready to send their Inbox to hell. There's a good chance that their Inbox count will be stuck at 666. The odds of this happening? 66.6%

Step 4: Highs and Lows

Life can be funny and sad. And by life, we mean the Internet as a whole. But often the text doesn't quite reflect that so we're going to be randomly adding "*sigh*" and "LOL!" to the ends of sentences. Much better now, right?

Step 5: Sarcasm Enhancer

Do you really believe everything you read? Whatever. Now the whole Interwebs will be as sarcastic as you feel on a Monday morning.

Step 6: What'd You Say?

People keep saying things. All over the place it's so-and-so said this, whatsisface said that. Doesn't anybody shout or enthuse or gush their thoughts?

They do now.
