Firefox Developer Edition, also known as Firefox Quantum, allows you to test out the latest development tools and features that will be added to the normal Firefox versions soon. 

What distinguishes the latest developer editions from prior versions is that they no longer use the Aurora channel as their foundation. They now base their operations on the Beta channel. 

Enhanced Engine to Attract Previous Firefox Users. 

The next-generation web browser engine allows Firefox to use nearly all of your computer's CPU cores. You'll notice faster performance within seconds of starting to browse with it. 

The primary purpose of this engine was to improve performance, although there were also enhancements to its privacy settings. For example, Quantum can disable internet trackers and protect your privacy. 

The Latest Firefox Helps Web Developers. 

This current Firefox version includes several exciting new developer tools. Previous tools are also included. Some of the most famous tools include the JavaScript debugger, which supports many browsers, and the CSS Grid, which allows you to design dynamic and complex web layouts. 

There are various new additions to the Inspector, Console, and Network tabs. For example, CSS work can now be completed using the Inspector. The Console now allows you to view in-line items and send group messages. 

The new "Photon" user interface features a redesigned appearance. 

The GUI design pattern of the interface is entirely new and feels more current. Square tabs have replaced curvy tabs. In addition, the new main menu is more organized than the previous one. 

The tab panel in Firefox Developer Edition is new and contains a list of recommended stories and most-visited websites. 

A completely revamped engine that appears new and performs better. 

Quantum has been a significant advance for Firefox in recent years, and it surpasses the competition. This will undoubtedly help bring the Firefox browser back into the mainstream.
