Steps to reproduce:

In version 106 of Firefox, the :where() selector seems to no longer be supported.

Open your console on any page and enter the following and hit return:

CSS.supports('selector(:where())')

Actual results:

The value returned is false

Expected results:

The value returned should be true

Component: Untriaged → CSS Parsing and Computation
Product: Firefox → Core

This is the correct behavior. You should use CSS.supports('selector(:where(*))'), or any other actually valid selector. See bug 1789248.
