Like Opera, Safari adds several built-in Real Simple Syndication features, including the easy addition of new RSS feeds, an RSS feed viewer, and a personal clipping service that aggregates RSS feeds into one bookmark.
For those who share a computer or browse at work, Safari's Private Browsing feature hides your cookies, browsing history, and caches as though you were not surfing at all. Safari also recognizes who is logged in to the Apple Mac OS so that parents can limit the sites their children have access to. Apple also claims improved Web standards support for Safari, such as CSS3 and DHTML, so more sites will render as their designers intended. But cooler still is Safari's integration with some native Mac OS-level features, such as Apple Command+Option+D, which lets you see the dictionary definition of any word found on a Web page.
Unlike Mozilla Firefox, however, Apple Safari RSS is not extensible. This means you won't profit from the wealth of handy plug-ins available for extensible browsers, such as Firefox.
Though Apple does not provide separate support for Safari, you can use Apple's built-in Mac OS Help Viewer or browse through Apple's online knowledge base forums. And reporting a bug (should you find one) is easy: simply click the "Report bugs to Apple" menu item on the desktop. In addition, savvy users might want to read Surfin' Safari, a blog by David Hyatt, the man responsible for designing much of Safari RSS.
