OverridePostUpdatePage

Override the upgrade page. If the value is an empty string (""), no extra pages are displayed when Firefox is upgraded.

The upgrade page, also called the "What's New" page, is the extra tab Firefox opens the first time it starts after updating to a new version. It is normally a page on mozilla.org describing what changed in that release. Setting this policy replaces that page and stops Firefox from using a page supplied with the update itself.

For the page shown the first time a new profile is used, see the OverrideFirstRunPage policy.
