Is it possible to support Seamonkey or IceApe?

I'd like to see tabtree on Seamonkey or IceApe. Currently it shows incompatible.

I use it on Waterfox Classic. I considered porting it to Seamokey but Seamonkey was somewhat different from Firefox in terms of tab management and UI code so there was no easy way to make TabTree run on Seamokey.

A SeaMonkey version would be awesome. Used SM a lot in the past, but in the years since, I've gotten so used to tree tabs and don't want to use any browser that doesn't have them. I would like to go back to SM, but without tree tabs, that's not going to be possible.
