Apple's Safari was initially developed for Mac OS, but it was later introduced to Windows (XP, Vista or 7). It is the default browser for Mac, but it doesn't rank very high in number of users. Standards-compliant, browsing with it is fast and secure, and supports HTML5, CSS3 and SVG. An interesting feature of this browser is that it removes advertisements and pop-ups and leaves just the text, to allow you to read any given article without being bothered by these. Like all browsers now, it enables DNS prefetching to allow users to make searches using the address bar.
