To repeat myself: 
it's got something to do with clang, your cpu and skia, and clang/skia enabling some parameters not supported by your CPU. Use specific -march (not native) or compile firefox with gcc (-clang use flag).

Sure VirtualBox can mess it up, I don't know exactly how. But try with GCC (-clang use flag).

(Host CPU is i7-9700)

changing /etc/portage/make.conf
COMMON_FLAGS="-O2 -march=skylake -pipe"

problem SOLVED
