Firefox DevTools hides unreferenced CSS variables
Stefan Judis · 2026-01-10 · via Stefan Judis Web Development

Here's a quick and handy addition to the Firefox DevTools.

Whenever you debug CSS that's full of CSS variables, it becomes annoyingly hard to parse everything going on in the DevTools because the custom properties are cluttering :root or * or whatever.

Chrome DevTools with open CSS panel showing tons of unused custom properties.

Firefox 145 (released Nov 11, 2025) now added a tiny adjustment that helps out massively.

Firefox DevTools hiding "52 unused CSS properties".

Love it!
