The website works best in Internet Explorer versions 6.0 and higher and Firefox versions 2.0 and higher. Users may experience issues with other browsers and are recommended to use the browsers listed above. It is recommended that browser windows be opened using the icon on the desktop to avoid shared browser sessions. Some browsers share sessions regardless of how the browser is opened. Please check with the browser's vendor about session management. When NPPES detects multiple browsers open within the same session, NPPES will terminate the session to protect the data in NPPES. Data entered will be lost and will need to be re-entered. Use of the Back and Forward browser buttons could result in loss of all the information entered. Users should use the Next and Previous buttons provided on the application to navigate between the pages of the application.
