1. A firing control system with multiple safeties for replacing a trigger bar and a trigger spring in a striker-fired semi-automatic handgun, comprising:
a base, installed inside a trigger mechanism housing of the pistol, having a front end and a rear end which is lower than the front end, wherein an arc surface groove is formed in the front end, and the rear end is concave to form a clamping platform;
a return spring, an end thereof is placed on the clamping platform;
a firing pin releaser, comprising:
an arc surface turning portion, rotatably mounted in the arc surface groove;
a limit protruding portion, formed on one side of the arc surface turning portion, stopping the arc surface turning portion from rotating toward a forward direction relative to the arc surface groove by contacting a first side plane of the front end;
a body portion, extended from and formed on the other side of the arc surface turning portion, wherein a limit side plane and a clamping surface are formed on the bottom of the body portion, the body portion stops the arc surface turning portion from rotating toward a reverse direction relative to the arc surface groove by contacting a second side plane between the front end and the rear end with the limit side plane, and the return spring is clamped by the clamping surface and the clamping platform clamp; and
a release portion, protrudingly formed on the top of an end of the body portion, for holding or releasing firing pin handle of a firing pin of the pistol; and

a trigger connecting bar, having a connecting portion movably linking to a trigger of the pistol, a linkage portion bent to bypass a magazine of the pistol and connected to the connecting portion, a guiding portion connected to an end of the linkage portion, and a trigger safety portion extended vertically from the guiding portion and movably located above the firing pin releaser, wherein the guiding portion is placed in a connector of the pistol, and when the firing pin of the pistol is ready to fire, the trigger safety portion suppresses the limit protruding portion upon the first side plane, so that the release portion is moved up by rotation of the arc surface turning portion to hold the firing pin handle.
