My server is zimbra 6.0.7_GA_2473.RHEL5_20100616201624 CentOS5 NETWORK edition. When I click 'Documents' tab in a user console, I see an error, ZmNotebookPageController is not defined. However it happens only by Firefox. IE displays the Documents tab without a problem. My firefox is 3.6.10. If you know something about this problem, please let me know.

Thank you,
