I found this after I started having issues with the ignore all in facebook.

I had to tweak the page it runs on to
http://www.facebook.com/home.php?ref=home#/reqs...

I also realized there appears to be a limit I am guessing of 100 items it will process. So that means 2 things, I had to run it multiple times and I waited WAY TOO LONG to get this script in the first place.

Places a simple Ignore All box on the lower right of your browser window. One click and all the request are ignored. Works for me! Thanks for your efforts, quite useful.
