Fright

Bit of a funny name for an add-on, but true. I am not even going to tell you what it does.

After you do know what it does, install it on all your friends' computers, and see if they like this add-on just as much as you do.

Wow, someone was so concerned about this add-on that they submitted it to Softpedia. well they say Fright is clean.

Note: After you install this extension, you must restart your computer.

FOR MY ENTERTAINMENT PURPOSES ONLY!

For those that really want to know how it works.
