Old, grizzled veterans of the browser wars ( Blood! Honor! W3C Standards! ) will remember OmniWeb, an expensive, Mac-only überbrowser that always seemed to be slightly ahead of everyone else. Well, it’s free now. A little background: OmniWeb is based on a slightly modified version of WebKit, but used to differentiate itself from other browsers with novel features. Ad blocking, tab previews, saved browsing sessions, inbuilt RSS reading, single-windows browsing and per-site preferences could once justify OmniWeb’s price, but now most of these features, and plenty more, can be found in free browsers.
