There are some security restrictions. The full article can be found in Adobe’s website. Two restrictions are very important:

1. “Users cannot enter text in text input fields while in full-screen mode. All keyboard input and key-related ActionScript is disabled while in full-screen mode, with the exception of the keyboard shortcuts that take the viewer out of full-screen mode. ”

   This restriction keeps most website/application away from fullscreen mode. Almost all websites and applications need keyboard interaction. Bringing the user out of fullscreen mode to fill up a form is not user-friendly.

   It was stated in Square Factor’s blog that the reason for disabling input is to avoid phishing activities. “…attacker could mimic the look of the operating system / browser to force user to enter sensitive data, such as passwords or serial numbers.”

2. “The ActionScript that initiates full-screen mode can be called only in response to a mouse click or keypress. If it is called in other situations, it will be ignored (in ActionScript 2.0) or throw an exception (in ActionScript 3.0).”
