Thanks for your patience. I didn't think getting a 32-bit Linux live distro would be so involved. But I guess with SSE2 issue with Firefox, and my lack of use anything but RHEL CLI in the last 4 years (well, a bit of Ubuntu in a VM once in a while), my knowledge is a little behind the curve.
Anyway, here's the inxi -Fxs output (from the box using FF 60.3.0esr)
