I am using an HDMI TV set to play a slideshow from my Macbook Air via a cable to Mini Display Port. Trying out different browsers, and I noticed this nifty "presentation mode" in Chrome browser. You can basically play the browser window content without any frame or tabs or even tools on the top of the browser (file/edit/view/history/etc). It shows only the content of the browser window and nothing else. Its seems to be so simple and I am looking for same mode in Safari, but cannot locate it. Does it even exist in Safari or Firefox? Thanks.
