Although the Firefox team has an entire page on the mozilla.com website dedicated to the new security features in Firefox 4, they seem to have forgotten to mention HTTP Strict Transport Security (HSTS).
While HSTS may not be the sexiest security feature for the average Joe, I was thrilled to see it implemented in the world's second most popular browser. Google Chrome has supported HSTS since September, 2009 in versions 4.0.211.0 and higher.
