Navigation pane does not load in IE/Edge when access to local storage is disabled


If access to local storage in Windows is disabled, the navpane does not load.
The navpane shows a message saying loading over and over, and a message like Access denied appears in the browser console.
There may also be an error like this:
TypeError: Unable to get property 'getItem' of undefined or null reference

Steps to Reproduce


  1. Begin in Windows 7, with IE11
  2. In IE11 navigate to Internet Options > Advanced and uncheck Enable DOM Storage
  3. Log into an instance on Helsinki

The navigation pane does not load, and continually displays the message Loading....


This can often be resolved by disabling protected mode or adding ServiceNow as a trusted site.
