No, L3 is not stable. L3 is a saddle point (stable in one direction, unstable in another). Look at the image below:
The red arrows indicate the unstable directions, and the blue, stable.

The only stable points are L4 and L5. However, we have (or will soon) put satellites at L1 and L2 for different experiments. They maintain their locations with thrusters.
