Firefox Beta and Developer Edition
Release Notes

Firefox is getting a major Visual Redesign (Photon project) activated on the Nightly channel and which will ship with Firefox 57 on the release channel.

AMD VP9 hardware video decoder support for improved video playback with lower power consumption

Accessibility indicator will now appear in the title bar of the window when Accessibility services are enabled

Added support for Date/Time input

Allow users to manage the site data

The browser's autoscroll feature, as well as scrolling by keyboard input and touch-dragging of scrollbars, now use asynchronous scrolling. These scrolling methods are now similar to other input methods like mousewheel, and provide a smoother scrolling experience

The content process now has a stricter security sandbox that blocks filesystem reading and writing on Linux, similar to the protections for Windows and macOS that shipped in Firefox 56

Middle mouse paste in the content area no longer navigates to URLs by default on Unix systems

Removed the toolbar Share button. If you relied on this feature, you can install the Share Backported extension instead.

Complete visual refresh of both the Light and Dark DevTools themes, matching the new visual style of Firefox Quantum

The Inspector shows the values of CSS variables on hover

Completely new and re-designed Console panel. Joining the Debugger and the Network Monitor, the Console has been rewritten using modern web technologies such as React and Redux. It now also allows inspection of objects in context.

On Windows and Linux, Firefox crashes occasionally on Intel Broadwell-U processors with old microcode. Windows users should ensure Windows Update is set to install updates. Linux users should ensure that the distribution package for Intel microcode is installed.
