(If I've filed this bug in the wrong sub-category, please adjust accordingly).

This bug has been opened to get the attention of the Solaris developers.

The description from that bug is included below.
Note that I've added the original bug submitter to the
interest list for this bug. If they are external-to-Sun,
then currently there is no easy way for them to update
the Bugster bug. That's been worked on.

If you need to ask an external-to-Sun original submitter
for further information, please consider adding a comment to
the OpenSolaris bug and get them to place it there.

Screenshot

I upgraded from B125 to B129. At Sun's website where I select download and
login using my contract login ID, Firefox freezes and must be killed. This
happens when trying to select/download SXCE or Solaris 10 from Sun's site.
However, if I go to sunsolve.sun.com and try to login with my contract ID, it
works fine.

Using the older Firefox currently integrated with Solaris 10 5/09 or 10/09,
everything works fine.

Please see attached screenshot of the frozen browser. I am logging this as
major because it prevents users from be able to use the vendor's own website.
