Notice to users of Netscape

Netscape versions 4.78 and 4.79

If you use Netscape 4.78 or 4.79, you may have difficulty viewing the pages of PKI. For example, the font may be very small, the displays may not be properly aligned, or images may be incomplete. The CRA is unable to correct all the presentation difficulties with these two versions.

Netscape 6.10

This version of Netscape is not fully compatible with some applications on our Web site. As a result, we are unable to provide full support for it. Later versions of Netscape are fully compatible with all applications on our Web site. If you experience any difficulties, please see the Netscape Web site for more information.
