Enabling the Plugin

• Note that Fullscreen API only works during user interaction (click, keypress, etc.).
• For security reasons accessing full screen requires the user's "permission", and so is tied to browser input events.
• It will work inside click/keypress/input events handlers, but can't be used without them.
  Check this: https://wiki.mozilla.org/Gecko:FullScreenAPI#Suggested_UA_Policy
  Otherwise, requestFullScreen outside a user action (e.g. a non-synthesized input event handler) is denied.
