AutomaticFullscreenBlockedForUrls

Block automatic full screen on specified sites

Supported versions

  • On Windows and macOS since 132 or later

Description

For security reasons, the requestFullscreen() web API requires a prior user gesture ("transient activation") to be called or it will fail. Users' personal settings may allow certain origins to call this API without a prior user gesture.

This policy supersedes users' personal settings and blocks matching origins from calling the API without a prior user gesture.

For detailed information about valid URL patterns, see https://go.microsoft.com/fwlink/?linkid=2095322. Wildcards (*) are allowed.

Origins matching both blocked and allowed policy patterns will be blocked. Origins not specified by policy or user settings will require a prior user gesture to call this API.
