Unable open secured 64bit website in Firefox

We got this when using Firefox2 open  EAServer.

It didn’t happen on production and our developers’ machine. Looks like a test certificate running on 64bit win server 2003 problem.

Solution:
Type in “about:config” in Firefox address bar to pop up the configuration window. locate the line named “security.ssl3.rsa_rc4_40_md5”, double click it to toggle it’s value to ‘true’.
