Safari and Firefox in Mac OSX have something called private browsing. In Google Chrome, it’s called opening an incognito window.
Google Chrome runs on Intel Macs running OSX Leopard or later. In incognito mode, Google Chrome does not store your browsing history or your search history. Temporary files, cookies, and download history aren’t kept either. They should all be gone after you’ve closed your browser (except for downloaded files should still be on your computer unless you manually delete them).
Incognito browsing is pretty handy if you are using a shared computer and you don’t want other people to see what sites you have visited.
Say you are shopping for a gift for a family member and you don’t want that person to see what where you’ve been doing your online shopping.
