Let it Snow par Vaultek

Let it snow is a lightweight Firefox extension that brings a new year atmosphere to your browsing experience. It allows you to inject a customizable snowfall effect onto any domain you choose, with full control over the density, falling speed, and wind-like swaying of the flakes.

The extension offers advanced styling options, including the ability to toggle between circles, squares, or realistic Unicode snowflakes. It uniquely supports CSS variables, allowing the snow to dynamically match a website's theme by pulling colors directly from the site's own stylesheets, all while maintaining high performance through GPU-accelerated rendering.
