Charger Light is Green when I plugged in my charger. And MacBook is not charging.

Try a SMC reset:

Install a temperature fan speed monitoring application.

Open Activity Monitor to ALL PROCESSES and set CPU to display values from high to low.

When your MBP gets hot, post images of both for review.

Run an Apple Hardware test:

Note that an error free AHT is not conclusive.

Ciao.

The data you have posted indicates that the temperatures are well within tolerable limits but the fans should be spinning a faster than just the default speed. What happens when you quit Fire Fox? Open some resource intensive applications that will increase temperatures to see if you can get the fans spinning faster.

Open the MBP and see if there is any accumulation of dust and debris. If so, clean it out.

I assume you reset the SMC.

Any results from the Apple Hardware Test?

Ciao.

I neglected to give instructions in regards to your charger.

Open System Information>Power and post this from your MBP:

Make certain that the charger is connected.

Ciao.

Thank you for the battery information and all looks normal, but you excluded the charger information. It may not make any difference.

Ciao.

I tried reseting SMC but failed.

I plugged in charger.

I shut down my MBP. then press shift+control+option and at the same time power button.

then release all keys, then again press power button. thats it.

Did the MBP turn on? If so, that is what is expected.

Ciao.

Your battery is being charged according to the System Information that you posted, so that is not an issue.

The question is the cooling fan operating correctly.

Have you run the Apple Hardware Test? It may provide a clue.

Ciao.
