Browser support Browser support varies for each version of the user interface (UI). Most major browsers are supported. Note: Some features have additional browser requirements, which are noted in the appropriate documentation. Table 1.

Setting Security Mode to High (via Internet Options > Security tab) is not supported. While UI16 and UI15 are supported on Internet Explorer 9, the browser may be slow when performing some operations. This does not necessarily indicate a performance degradation in the instance. Internet Explorer 11 is susceptible to memory leaks, which may impact performance, especially in Windows 7. Safari notes For Safari version 5 and Internet Explorer versions 7 and 8, the user interface automatically redirects to UI11. There is a security issue in some versions of Safari. User credentials may be disclosed to an unexpected site via autofill. For more information, see the Apple security update. Starting with Safari 9.1 and future versions of Safari, the leave page / stay on page pop-up message will only display once. Exceptions to general browser supportCertain applications and features in the Geneva release have browser requirements that differ from the list of browsers generally supported by the ServiceNow platform.
