Firefox regular on the left, Firefox Developer on the right. When you install Firefox Developer, you don’t have to worry about it affecting the setup you currently have with regular Firefox; you can install both applications side by side and they will function independently. This is due to Firefox setting up different user profiles for each. Mozilla has switched Firefox to a rapid release development cycle which means new versions will come more frequently. The non-profit organization has promised to push out a new stable build every.

The beautiful thing about the developer edition is that anyone can use and test it. Of course, you don't want to use this as a daily browser, especially in work situations.
Otherwise, we enjoyed using the new Firefox so much; we might consider switching back.
Firefox Quantum Developer Edition focuses on the new CSS engine designed to be the fastest, most powerful Firefox to date. Of course, since it is the developer version, the features focused on are for developers, including:
Inspector allows you to inspect and refine code to build pixel-perfect layouts.
The Console can track CSS, JavaScript, security and network issues.
The Debugger is a powerful JavaScript debugger with support for your framework.
Monitor network requests that can slow or block your site.
Add, modify and remove cache, cookies, databases and session data.
Test sites on emulated devices in your browser.
Fine-tune animations, alignment, and padding.
Unblock bottlenecks, streamline processes, optimize assets.
Find memory leaks and make your application zippy.
The only developer tool for inspecting the Web Audio API.
Edit, write, run and execute JavaScript in real-time.
Edit and manage all your CSS stylesheets in your browser.
If you're not a developer, you might consider using the latest end-user beta instead. It changes frequently, but you can always find it in the most recent Mozilla Firefox release.
