Safari 8.0.7, 7.1.7, and 6.2.7

Apple has released Safari 8.0.7 for OS X 10.10 Yosemite, along with Safari 7.1.7 for 10.9 Mavericks and Safari 6.2.7 for 10.8 Mountain Lion, with all three receiving improved performance thanks to a reduction in Safari’s memory usage, as well as a fix for an issue that enabled a Web site to prevent you from navigating away from a page using JavaScript alerts. Additionally, the three versions of Safari receive several security fixes, including one for an issue with PDF-embedded links that could lead to cookie theft or user information leakage, and others for vulnerabilities associated with WebKit page loading and WebSQL database access. All three versions of Safari are available
only via Software Update. (Free)
