In a website that gets fonts from Google’s CDN, the browser window loading icon continuously runs. In Firebug you can see that the WOFF file from google is the culprit.
Turn off Firebug. Apparently it’s a problem with Firefox/firebug that causes this issue. Once you turn off firebug the website loads and no loading icon is shown. The issue may be related to this, but not sure: http://code.google.com/p/fbug/issues/detail?id=4649
