Script Summary:
Regularly checks your Facebook friends to check whether anyone has removed you from their friends

INSTALL 
how do i use this?? 

When the script detects that someone you used to be friends with is no longer one of your friends, a message will appear informing you about who it was and giving a link to their profile page.
The script checks by default once per hour when on Facebook, but this time can be increased through "Tools > Greasemonkey > User script commands... > Set time interval to check for removed friends...".

Brief explanation of how the Script works...

Any time a page is loaded on Facebook, the script will run and it will follow the following basic algorithm;

• If the script has checked your friends in the past <> hours, do nothing.
• Otherwise, load a page on Facebook with a list of all of your friends.
• Go through each of these friends and add them to a list.
• Compare this list with the list saved the last time the script checked your friends.
• If someone was on the list before who isn't now, post the box informing the user.
• Save the new list of friends over the old one.
• Save the current time as the last checked time.

If you have any comments on this then please create a discussion about it.
Please don't create one complaining about it not working though if immediately after installing it nothing happens.
