If you have a vise, clamp the freewheel tool in the vise and use the wheel as a lever and turn it counter-clockwise. It could be frozen on pretty tight. Once it breaks free, take the nut off the axle and finish unscrewing the freewheel. Once it is off, you don't need a tool to put it back on, since the pedaling tightens it. Put a bit of anti-sieze on the freewheel threads to make it easier to remove next time.

That Fuji really cleaned up nice. On your front wheel, most people put the quick release lever on the left side.
