What’s new in Firefox 56

We’re just another version away from getting Firefox Quantum aka Firefox 57, with Photon UI. Firefox Screenshots tool is now available to all users and available for access on the toolbar by default.

This version of Firefox has added auto-fill functionality in the browser (en-us only).

Preferences have been reorganized into four sections from eight. Search functionality added to the preferences makes easy to find a setting/option.

You can turn the new Preferences off and revert to old options UI, for that, check Firefox 56 : How to disable new Preferences UI.

Media in a background tab will not be auto played until you select or focus on it.

Mozilla introduced about Firefox features through onboarding tour which appears when you click on fox icon in the new tab, you can disable or hide the onboarding tour if you want.
