In bug 1308636 [1], I plan to unship all -moz-prefixed multi-column properties defined in CSS Multi-column spec [2] and -moz-column-gap [3].
We've shipped column-span in Firefox 71 [4] and completed the support of all the properties in the multi-column spec. Other standard properties have been shipped since Firefox 52 [5]. We now have a solid foundation to unship the prefixed ones. I added a new pref "layout.css.prefixes.columns" and set its default value to "false" to guard the prefixed properties behind. If any serious web-compat issues arise, we can have those prefixed properties back.
