Love the script, but it's kinda broke on Firefox 2 on MacOS.
Here's a picture of the layout weirdness: http://i42.tinypic.com/2qcgsjq.jpg
Also, I've used the script for a long time, but strangely, I only recently noticed a weird problem: Where there are two or more deleted posts visible on the main page, visiting one, then hitting Back to return to the main page, makes the others no longer visible.
You can see this in the picture above -- I visited the deleted post #81233, and when I came back to the main page, the only directly below it, #81232, was no longer visible. (I can still visit it directly by URL.)
