I suspect this might be the nVidia driver creating a file that can be mmapped for use in a shared-memory protocol. Open source graphics drivers (particularly Wayland) use files in XDG_RUNTIME_DIR[1][2][3] for a similar purpose, but for whatever reason your driver is writing them to disk instead of putting them in a tmpfs? If you want more information about what the proprietary nVidia driver is doing, I'm afraid your only recourse is to talk to nVidia.

If Firefox is legitimately doing 3D graphics, then it would be sensible to include the abstractions that represent "everything you need to do 3D graphics", including <abstractions/nvidia>.
