OverridePostUpdatePage

Override the upgrade page.

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.

Values

OverridePostUpdatePage expects the URL to show the first time Firefox starts after an update:

A URL, such as https://example.com, replaces the What's New page with that page.
An empty string ("") shows no page after an update.
