The tests below are for JavaScript GUI objects that aren't part of Core JavaScript or the Document Object Model. These simply write the values of properties and methods listed on the Mozilla Developer Network into a table. Since some of these apparently require a secure context for Javascript to access them, forced https links are provided as well. If the SSL certificates are working, the links on the left may already be https.

• history (force secure)
• location (force secure)
• navigator (force secure)
• screen (force secure)
• window (force secure)
