[FIXED] How do you enable :has() selector on Firefox

Issue

When I check the :has() css selector on caniuse.com, it tells me that since Firefox103 it has been "Supported in Firefox behind the layout.css.has-selector.enabled flag". So how do I find this flag and enable it?

Solution

Go to the Firefox about:config page, then search and toggle layout.css.has-selector.enabled.
