display:-moz-box and display:-moz-inline-box have been deprecated

Published: | Categories: CSS


The non-standard -moz-box and -moz-inline-box values for the CSS display property are now considered deprecated and disabled by default in Firefox Nightly and early Beta/DevEdition. Assuming no major issues arise, these values will be removed from all the channels in the near future.

Note that other non-standard values for the display property, including -moz-grid and -moz-inline-grid, have already been dropped with Firefox 62.

Update: These values have been removed with Firefox 64.
