Firefox Pranks!

Firefox Pranks!
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
- Highs and Lows
- Sarcasm Enhancer
- What Did You Say?
- For real
- Watch it
- Dsmvwlr
- Total Confusion Combo Pack!
(Updated 3/30)
- Total Confusion Combo Pack! (non April Fools' Day version)


If you want to hit your victim with everything, you can go for the Total Confusion Combo Pack. The combo pack is set to only work on April 1st, so you can install it now, and nothing will happen until then. Also, throughout the day, the pranks become more and more frequent!

IMPORTANT:
 All of these can be removed simply by going to Tools > Add-ons and uninstalling them.


Scripting by zachninme. Without whom this would not have happened.

These add-ons started out as Greasemonkey scripts and were converted to add-ons with this script compiler.

All code linked to, and mentioned in this Instructable is licensed under the GPL.

UPDATE (3/31/2010): I made these scripts a while ago and haven't tested them since then. Since youtube removed the rickroll video it does not work any more. You are more than welcome to substitute a new video in that script or change any of these for that matter.

Step 1Two Steps Back

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.

I love the add on compiler. I have made like ten of these and are now looking to unleash them all.... Just need someone to mess with..

This is great, but the link to the all-in-one pack failed to download, and the Rick Rollr link was removed. I tried going to Roll Tube and recompiling the source with one of the other rick-roll videos, but it didn't work at all.

Would there be any chance of this being updated and re-released?

Thanks for sharing these. So funny. I have played with changing the source code, which is great because I didn't know you could make Firefox add-ons so easily. I'd like to modify the Rick-roll code, but the link to the source seems to be broken. Could you check it please?

Thanks!

Thanks so much. Brilliant, it worked a treat. I have set one up to redirect to that mind-numbingly awful batman thing: http://www.youtube.com/watch?v=NrmPehlHK3w

My wife is going to hate me ;)

How could I change the link the person is sent to? Could I easily bother them with other random links?
Apr 1, 2010. 9:49 AMtravisttt says:
OK, I've become slightly smarter and have found where add-ons are stored. Inside of the firefox profile, where can I find this file?

How come i cant download?
Mar 31, 2010. 4:50 PMcompgeek_brad says:
 Is there any chance we could get the greesemonkey scripts??
the plugins are good but a lot of people i know use Google chrome, which wont support them (but natively supports greesemonkey)

this 'devils inbox' trick is based on an interesting number in the bible which is 666. The Devil is generally associated with the number, as is a weird character also mentioned in the Bible who we know as 'The Beast'. Who could this character be? We've only to wait and find out.
May 30, 2009. 6:46 PMlunchboxslayer27 says:
either michael jackson or rick astley..

we don't know. I told you that.
Feb 4, 2009. 9:46 PMNamasteNick says:
is it easy to undo?
Feb 26, 2010. 10:26 PMerikals says:
Yes. Click Tools>Add Ons, then click the 'gmailinboxer' addon and choose Uninstall. When prompted, click 'Uninstall'. Wait until you see a notice that says 'Restart Firefox to apply your changes.' Next to that notice there will be a button that says 'Restart Firefox.' Click that, then wait a while for Firefox to install the add on and open up again.
