Does the issue still exist in Safe Mode? http://support.mozilla.com/en-US/kb/Safe+Mode

I know Bug 527944 is related to blackboard but that is only during login so don't think that applies here.

FWIW - works for me on 3.5.5 on XP

Works in Linux too.  The problem is Mac specific.  Ignore the second line on that netstat info.

Is there a downloadable build with debugging enabled?  The Mac is my wife's and I don't want to learn how to set up a build environment on Mac.

You just get a white page? If you view -> Page Source is there anything shown? Can you continue to browse other sites while this occurs (i.e. in another tab or window).

Before going to the page go to Tools -> Error Console and select Clear. Load the page. Are there any errors shown in the Error console now?

It works for me on Mac OS X 10.6:

mpapet -> Are you still experiencing this issue with the latest FF version?

Close the bug.  Spending some time on the issue with a packet sniffer, I discovered the issue was at the TCP/IP stack.

The OS has been upgraded and the problem went away.

View->Page Source was empty.  Other tabs worked.

Why blackboard's site and not every other site opened in another tab?  No clue. I didn't dig at it long enough to find out.

Glad the issue has been resolved.
