Using the Social API, you can chat with friends, see notifications and other information directly in the browser.

Firefox 17 also comes with a preloaded HTTP Strict Transport Security (HSTS) list to improves security when you are connecting to websites present on the HSTS list. When HSTS list is used by Firefox, it can decide if a secure connection needs to be established when connecting with a website. When the list is not present, the browser first connects with the host server of the website to decide if it needs a secure connection, which makes it easier for an active network attacker to carry a man in the middle attack and prevent the browser from connecting securely.

The latest Firefox version is no longer compatible with Mac OS X 10.5 or earlier. ESR (extended support release) users can also upgrade to Firefox 17 ESR versions of the web browser.
