--- Comment #1 from Jan Beich <jbeich@FreeBSD.org> ---
Caused by files/patch-bug1559213. AOM_PLANE_ALPHA was removed in
v1.0.0-835-gf1570f0c2 (2018-10-10 snapshot) but Firefox 93 still bundles
v1.0.0-611-g1e227d41f (2018-08-06 snapshot). Firefox uses dav1d by default for
AV1 video since 67 and for AVIF images since 78. A quick fix would be to drop
alpha references until it builds but the proper fix is to get rid of bundled
libaom or update it to a newer snapshot.

Switching back to the bundled version isn't a good idea e.g.,
