I've been using Windy for years and thoroughly love it. But lately there's a problem with particle animation in my Firefox web browser. When I first load the page, the animation looks right, but then when changing the forecast time, forecast model, or switching between wind and waves, the particles never change. They always continue showing the original velocity and direction.
The android app on my phone works fine, and I can see the animation change whenever I change the forecast parameters. But it'd be nice to have this working again on the big screen.
