Fixed version by me: http://pyrczak.pl/j-A_160864.user.js
Tested and should work on Firefox and Chrome/Chromium (On my Chromium i don't even need TemperMonkey, just drag&drop to extensions window)
License the same as this on github: CC-BY-NC-SA.

Interesting - I've got Tampermonkey (using Chrome) installed and when I clicked on your link, Tampermonkey took over and asked if I wanted to install the script.
(Neatnick in me taking over now...) Out of curiosity, is there any chance of you creating a userscripts.org page for yourself and then hosting the script out of there, since that's kind-of the place for that stuff? I noticed that one of the lines in the script itself is:
// @namespace http://userscripts.org/users/508112
Which points to the page for the original author. Not a big deal, I suppose, but I figured no harm in asking.
Thanks for getting it working again and posting the fix!
Any chance that a forum moderator can put that link into the first message of this thread, since the link that's there goes to a version that no longer works with the current version of the WME?
