How do you enable :has() selector on Firefox
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.
