[jQuery] cluetip plugin crashing Firefox with external style sheet

When using the cluetip plugin, I am loading an external url. The tip
loads fine if my external page is plain text/html, however if I
reference an external style sheet (using the <rel> tag), the plugin
crashes Firefox. It's happened more than once. Is there a workaround
for this other than inline style? I need to use a .css file since I
have multiple pages to show with the cluetip.

Thanks!
