A redesigned interface with a clean, modern appearance, consistent visual elements, and optimizations for touchscreens
A unified address and search bar. New installs will see this unified bar.
A revamped new tab page that includes top visited sites recently visited pages, and recommendations from Pocket (in the US, Канада, and Germany)

Firefox now exclusively supports extensions built using the WebExtension API, and unsupported legacy extensions will no longer work.
The browser’s auto-scroll feature, as well as scrolling by keyboard input and touch-dragging of scrollbars, now uses asynchronous scrolling. These scrolling methods are now similar to other input methods like the mouse wheel 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.
Some older versions of the ATOK IME, including ATOK 2006, 2008, 2009, і 2010, can cause crashes and are therefore disabled on the Windows 64-bit version of Firefox Quantum. To fix those incompatibility issues, please use a newer version of ATOK or one of the other IMEs.
The default font for the Japanese text is now Meiryo

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 the 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 the inspecting of objects in context.

Users running Firefox for Windows over a Remote Desktop Connection (RDP) may find that audio playback is disabled due to increased security restrictions.
Users running screen readers may experience performance issues and are advised to use Firefox ESR until performance issues are resolved in an upcoming future release
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.
