This was posted in a private forum about a fix for the Monsterkill script per MD:
Your probably having the problem i had. Monsterkill stores some kind of data in the about:config file. Anyway, its possible for Monsterkill to get too full of data and you need to completely uninstall it and all its preferences and reinstall for it to work again.
Once i did that, it started working again.
To delete the preferences, open up the Greasemonkey console, theres a checkbox at the bottom that says "also uninstall associated preferences". Check that box, then select Monsterkill(both versions if you have both) and uninstall.
Then reinstall Monsterkill V2 and it will work.
