Safari (web browser) support, which can make JavaScript loading up to 50% faster. It also has built-in crash resistance unique to Snow Leopard; crash resistance will keep the browser intact if a plug-in like Flash player crashes, such that the other tabs or windows will be unaffected. Safari 4.0.4, released on November 11, 2009 for both OS X and Windows, further improves JavaScript performance. Safari was one of the twelve browsers offered to EU users of Microsoft Windows in 2010. It was one of the five browsers displayed on the first page of browser choices along with Chrome, Firefox, Internet Explorer and Opera.
