May be simple:
tell application "Safari"
activate
if (count of windows) is 0 then
make new document at front
end if
tell application "System Events" to keystroke "f" using {command down, control down}
end tell
Not sure if you can do this without a toolbar.
Update 4/4
not sure what you can do with it, but look at this program. If it works the way you want. Add system events to use the drop-down lists to select an item.
The Barbarian Group has a free app called "Plainview", which seems to be a wrapper for Webkit. It works as a “full-screen kiosk-style presentation content viewer,” similar to how Chrome's presentation mode works.
