If you enable or don't configure this policy, users can change the URL in the address bar. If you disable this policy, it prevents users from changing the URL in the address bar. Note: This policy doesn't prevent the browser from navigating to any URL. Users can still navigate to any URL by using the search option in the default New Tab Page, or using any link that leads to a web search engine. To ensure that users can only go to sites you expect, consider configuring the following policies in addition to this policy: - 'NewTabPageLocation' (Configure the new tab page URL) - 'HomepageLocation' (Configure the home page URL) - 'HomepageIsNewTabPage' (Set the new tab page as the home page) - 'URLBlocklist' (Block access to a list of URLs) and 'URLAllowlist' (Define a list of allowed URLs) to scope the pages that browser can navigate to.
