Version 60.0, first offered to Release channel users on May 9, 2018
Firefox 60 offers something for everyone and a little something extra for everyone who deploys Firefox in an enterprise environment. This release includes changes that give you more content and more ways to customize your New Tab/Firefox Home. It also introduces support for the Web Authentication API, which means you can log in to websites in Firefox with USB tokens like YubiKey.
Firefox 60 also brings a new policy engine and Group Policy support for enterprise deployments. For more info about why and how to use Firefox in the enterprise, see this blog post.
Thank you to all of the new Mozillians who contributed to this release of Firefox!
