It seems to work fine with my Fedora 27 system (Mozilla/5.0 (X11; Fedora; Linux x86_64; rv:59.0) Gecko/20100101 Firefox/59.0) using a GeForce GTX 1080 Ti/PCIe/SSE2 running proprietary linux drivers (v390.25).
Not with the stable version, but Firefox nightly (61.0a1) seems to work very well (with optirun to run it with NVidia card, see parent comment). Better than Chrome actually.
