I'm having the same problem as this post:
after an upgrade to 6.0.5 last night. Reinstalling like that other person did isn't really an option -- too many users and too much downtime.
We haven't made any changes to the splash screen; it's just stock Zimbra NE 6.0.5.
Error: this.mDownBoxAnimate is undefined
chrome://browser/content/tabbrowser.xml Line: 3179
That line is
this.mDownBoxAnimate.style.opacity = percent;
mailbox.log shows reports

and it just sits with no further connection data until it times out with 'requested session no longer exists.'
Any ideas? We need to get into the Admin console.
