Firefox shows error, stops my slideshow from running

I'm getting this error in Firefox:

Timestamp: 6/24/2013 11:06:53 PM
Error: TypeError: url is undefined
Source File: http://dev.tgci.com/sites/all/modules/colorbox/js/colorbox_load.js?moxq6l
Line: 14

I spoke with one of the Drupal developers over on IRC and he said it appears that this is getting in the way of my slideshow running (it's a simple Views Slideshow). When I turn off colorbox, the slideshow will work. When I turn it back on, the slideshow stops running. He said it appeared to him that this script error was the problem.

Thank you for any help you can give me.
