Userscripts.org

Firefox is reporting some errors on the arena page when I hover by an enemy button for the first time.

The error message is:
"Permission denied for <http://[ENEMY].mybrute.com> to call method Location.toString on <http://[MY_CURRENT_BRUTE].mybrute.com>."

Looks like an odd cross-domain scripting issue. Beats me.

Another error which shows up as the page is loaded is:
Error: thebutton is null
Source File: (...)/gm_scripts/my_brute_manager/my_brute_manager.user.js
Line: 1113

Maybe a threading problem here?

My environment:
Firefox 3.5.6
Greasemonkey 0.8.20090920.2
