JIRA v6 freezes, can not click on dropdown menus

JT4

We've installed JIRA v6 in our test environmet. We have noticed that the dropdown menus - Dashboards, Projects, Issues, Agile, Help, Administration, and User all freeze. We are unable to navigate or logout of the instance.

The logs are not showing any errors or messages. We are using FireFox.

Has any one else run into this issue?

If you upgraded JIRA, make sure you clear your cache (twice, just to be suer). Otherwise, check with Firebug if there are any errors on the console ....
