Version 56.0, first offered to Release channel users on September 28, 2017

Today's release gives Firefox users a better experience with features like Firefox Screenshots, Send Tabs, and more control over the browser with an improved (and searchable) preferences section. It also includes incremental performance improvements that move us closer to our biggest release of the year, coming in November.

We'd like to extend a special thank you to all of the new Mozillians who contributed to this release of Firefox!
