Two windows open in Firefox 3

When you click a page or a link that opens a dialog in the author environment using Firefox 3.x, two windows open.

Solution

As a quick workaround, comment the line 1374 in /libs/CFC/templates/Admin/List.esp (or if you overlayed look in /apps/CFC/templates/Admin/List.esp)

......
// --- workaround for firefox behavior --- if (!ie4) location.href=myLinks[fini].link.href;
