All your answers are based on firefox being open- I CANNOT OPEN FIREFOX IN ANT FORM!! Hence my original question!!!!!!!!

-> press CTRL + SHIFT + ESC keys to open Task Manager -> Processes tab -> right-click firefox.exe and click End Process Tree -> close Task Manager

-> Start Firefox in Safe Mode by holding down SHIFT key while starting Firefox

• As an alternative method, by using Win + R key combination and enter one of the following in the Windows Run box:
  • firefox -safe-mode
  • "C:\Program Files\Mozilla Firefox\firefox.exe" -safe-mode
  • "C:\Program Files (x86)\Mozilla Firefox\firefox.exe" -safe-mode

-> Firefox Safe Mode window will appear -> DON'T SELECT ANY OPTIONS, just click Continue in Safe Mode

After that, perform the suggestions mentioned in the articles provided in my previous post. Also see this - Firefox will not start

Check and tell if its working.
