NOTE: The only supported Web browsers that properly display geographic location and depth on the interactive, geospatial profiles are Internet Explorer 8 for Windows and Firefox 3.6 or greater for all platforms. Use of other browsers may result in spurious or no information given in the status window. Firefox may be downloaded at http://www.mozilla.org/products/firefox.

Browser setup:
For all browsers, the status bar and JavaScript must be enabled. Firefox also requires "Change status bar text" to be checked under Advanced JavaScript Settings.

If using Internet Explorer 8, you must disable scripts/ActiveX controls. To do this, click the information bar (found at the top of the page), then click "Allow Blocked Content...", finally, select "Yes".
