### Firefox DevTools Challenger

Rachel Nabors worked with Mozilla on this interactive, nautical-themed project showcasing the new animation debugging tools of Firefox Developer Edition 44 .

Journey through the ocean and test out the tools with weird and wonderful undersea creatures! (You’ll need to download Firefox Developer Edition to make the most of it, naturally.)

You can read some of Rachel’s extensive writings about CSS animation over on her blog .
