devel/icu major updates aren't ABI-compatible, so each update requires
rebuilding every consumer. This is usually done by bumping PORTREVISION.
As www/waterfox was removed before r482830 it missed rebuild thus still
depends on the old shared library version.

Easy way is libmap.conf but it may lead to application crashes.

Either rebuild www/waterfox from the last revision before removal or
downgrade devel/icu to 62.1 if nothing else requires 63.1. In the former
case you can also update the port (adjust DISTVERSION then run "make
makesum") assuming no patch conflicts.
