Mozilla UX built a feature directly into a real browser build to stop prototypes from lying
Mozilla's UX team embedded the 'Report Broken Site' feature into a local Firefox Android build using AI, getting real network conditions and branching logic that Figma's predefined paths can't replicate.

Audit your next usability study to check whether failures are caused by the design or the prototype's constraints, and consider native-build testing when branching logic is complex. — Designer's Takeaway |

Figma's data science team publishes actual time-savings measurements for Figma Make
Figma's internal data science team stopped assuming AI saves time and built a research method to measure it, publishing their approach and findings for Figma Make.

Read Figma's methodology before claiming AI speeds up your team's workflow, then use it as a template for running your own internal productivity measurement. — Designer's Takeaway |

Smashing Magazine breaks down how to keep tight control over motion when designers and developers share animation ownership
Alexey Kopytin explains using Lottie animations with DOM events and distance-based math to build a tactile squeeze-toy experience, keeping developer implementation faithful to the original design intent.

Use Lottie as a handoff contract for complex motion so developers implement exactly what you specified, rather than reinterpreting keyframes in CSS. — Designer's Takeaway |
Today's Idea
Your prototype is also a research instrument, and it has its own bugs
Two stories this issue point at the same underlying problem: the tool you use to test your design shapes what you can learn from it. Figma paths constrain user behavior in ways that contaminate usability findings, and Lottie animations break down during handoff when motion intent isn't encoded precisely. Before your next study or handoff, ask whether the fidelity of your prototype matches the fidelity of the question you're trying to answer.
