Back when it became the most popular alternative to the then-dominant Internet Explorer, one of the best features of the Firefox browser was its speed. Its competitors caught up and crushed it in that regard long ago, but today marks the launch of a new version of Firefox that might turn things around. The latest release, simply numbered 57, brings Project Quantum's changes to the main release channel.
If you use Firefox, you probably have already upgraded to the latest version. If you don't, maybe it's time to give Mozilla's alternative browser another shot.
