Take a look at a dependencies of firefox-esr
https://www.freshports.org/www/firefox-esr/

in build dependencies:
gtk3>=3.14.6 : x11-toolkits/gtk30

in library dependencies:
libgtk-x11-2.0.so : x11-toolkits/gtk20
libgtk-3.so : x11-toolkits/gtk30

quite confusing gtk20 vs gtk30...

gtk20 has not option WAYLAND so you need to rebuild gtk30 with option 
WAYLAND enabled.
