Context
Every major browser treated video-in-a-floating-window as something websites opt into — YouTube decides if you get it, not you. The challenge was to give Firefox users that control natively, without waiting for site owners to build support for it.
My role
UX lead for the project from inception through delivery, working with a product manager and two developers.
What we did
We shipped Picture-in-Picture as a browser-level feature available on any site, not something sites had to individually support. Under the hood, this meant taking a position in an unsettled area of web standards — Safari and Chrome had already shipped narrower, developer-gated versions built around an evolving W3C spec.
Impact
Shortly after launch, Chromium-based browsers began shipping their own toolbar-level Picture-in-Picture controls, and Firefox's approach reopened parts of the API standardization conversation around what belongs to users versus site owners. It's a small feature by surface area, but a clean proof point that even a product as commoditized as a browser has real room to differentiate on user-centered design — the kind of thing people don't expect until it's in front of them.
