Sorry if you felt forgotten.
The best you can do is report on
K-meleon Goanna thread and if the latest build, that has the latest engine update by roytam, still doesn't work, there is no hope.
Have in mind that K-meleon, uses an "old" engine (at the rate of engines versioning out there) and have these "flaws" (not the browser shell, but the engine), specially with sites like FaceBook and similar mainstream sites.
It is an annoyance, but facebook still works (note I said still...) on m.facebook.com
