Safari. It’s the browser in OSX. I keep using it because it’s there, but honestly, I wouldn’t miss it if it wasn’t on there. Apple’s done a decent job with it, and for the most part, it does what it is supposed to.
Safari has a Private Browsing mode that doesn’t keep a webpage history, form information, downloads, and searches.
“Wink, wink. Nudge, nudge. Say no more, say no more.”
Now add the fact that you can rename menu items in Safari fairly easily, and you get this, more accurate moniker.
