Just downloaded Firefox 50.0.2 to Mac running 10.9.5

2.66 GHz Intel Core Duo, 4GB 1067 Mhz DDR3

This is a new install, not an upgrade.

Firefox instantly crashes and will not launch. Will not start in safe mode. Has to be closed with forced quit. Tried reloading Firefox 4x times and re-booted computer several times. Will not work.

Thank you.
