They've integrated Firefox Share with Firefox Hello, which means that users will be able to open video calls through links sent over social media. Internally, the browser dropped support for the insecure SSLv3 and disabled use of RC4 except where explicitly whitelisted. The SafeBrowsing malware detection now works for downloads on OS X and Linux. (Full list of security changes.) The Mac OS X version of Firefox is now running Project Silk, which makes animations and scrolling noticeably smoother. Developers now have access to the powerful Fetch API, which should provide a better interface for grabbing things over a network.
