Is 全画面(フルスクリーン)化 for DMM/FANZA Games safe?

Adds a fullscreen button for supported DMM/FANZA browser games.

This extension displays a button near the upper-right area of supported DMM/FANZA browser games to switch the game view to fullscreen. It removes extra on-page display elements where supported and may enlarge games that cannot be fitted exactly; returning from fullscreen typically uses the Esc key, depending on the browser.
