Autofocus will work only if the effective aperture is within the range of the camera (currently f/8 with most EOS cameras).
The Canon 1.4x extender (also known as a teleconverter) will multiply the focal length of the existing lens by 1.4x, and will cut back the amount of light by one f/stop. For example, using a 1.4x teleconverter with a 300mm lens will effectively increase the focal length to approximately 420mm. A lens set to f/2.8 will now be f/4.
Teleconverters are best used with longer telephoto lenses and are not recommended for lenses wider than 50mm, e.g. 28-105mm (35mm format
