I am losing antifreeze no leaks and white smoke

SOURCE: losing a gallon of antifreeze every 50 miles

try some rad weld added to the resevior it will plug any small leaks that you wouldn't notice

SOURCE: 95 escort smoke from vents vibration when accelerating why??

The smoke you could be seeing may be steam, your heater inside the vehicle may have a leak and causing steam to rise out of the vents, if you are smelling the steam this is what I suspect.
Engine vibration could be a number of things, check the engine mounts to start, one of them is probably broken.

SOURCE: no heat, enginge died, antifreeze leaked, won't start again

car overheated.after it cools off try to start it again, if it dont start...check oil and see if it lookd like water is in it(milky)....if the oil looks like its milky or sludgy ..you may have a cracked head...thanks

SOURCE: white smoke coming from the exaust. losing water,

I don't know what engine you have, but is usually caused by an intake gasket leak, or a head gasket leak

SOURCE: Started white smoking and losing

if you are losing coolant and and producing white smoke from the tailpipe you have the classic sign of a bown head gasket. usually this smoke is accompanied by a bitter sweet odor. most common causes are severe engine overheating or severe misfire(flashing check engine light). take the car in for a diagnosis.
