Apple's new "Resume" feature in Mac OS Lion allows you to open and close documents without having to worry about saving or losing data. And when you re-open the application, it brings you back to the exact point in a document where you last left it.

However, when browsing the web, this can be quite annoying. If you close Safari with 10 tabs left open, then they will all immediately re-open when you start up Safari again.

To get around this, quit Safari in Mac OS Lion by pressing press cmd + option + Q instead of cmd + Q. This will quit the application and close all tabs.

When you re-open Safari, you are only left with whatever your default setting is for opening a new window. I have mine set to "Open a blank page" so that is what I get when I open Safari.
