In addition to the stable release of Firefox 42, Mozilla also launched Firefox 44 Developer Edition, adding visual editing and memory management tools. Today’s release coincides with the one-year anniversary of what Mozilla calls “the first browser created specifically for developers.”
Firefox Developer Edition sits between the Nightly and Beta channels. Firefox development starts with Nightly, which consists of the latest Firefox code packaged up every night for bleeding-edge testers, is followed by Developer Edition, which includes everything that is labeled as “experimental,” then Beta, and then finally the release channel for the broader public.
The new visual editing tools in Firefox Developer Edition include Animation Tools that Mozilla says “work the same way animators think.” The memory management tools, meanwhile, are designed to help developers understand memory performance and websites.
Here’s the full Firefox 44 Developer Edition changelog:
- New: Improved warning pages for certificate errors and untrusted connections
- Changed: Warning page when RC4 is the only supported cipher
- Developer: Right click on a logged object in the console to store it as a global variable on the page
- Developer: Application/JSON documents can be easily inspected using interactive viewer
- Developer: Visual tools for Layout and Styles: Display rulers along the viewport to verify size and position and use the measurement tool to easily detect spacing and alignment problems, Use CSS filters to preview and create real-time effects like drop-shadows, sepia, etc
- Developer: New memory tool for inspecting the memory heap
- Developer: Lock icon strikethrough for pages containing insecure password fields
- Developer: Visual tools for Animation:View/Edit CSS animation keyframe rules directly in the inspector, Visually modify the cubic-bezier curve that drives the way animations progress through time, Discover and scrub through all CSS animations and transitions playing on the page

- Make sure you’re interested in the above before you download Firefox Developer Edition. If not, the stable or even beta channel are probably better suited for your needs.
