Did you install the India FF version?

Is the screenshot from inside Firefox itself or somewhere else?

No. I took it from outside as to show you what I needed. Just for your reference only. I want that format on browser.

Your suggestion will only change the language of the browser but MY MAIN MOTIVE IS TO GET DATE-FORMAT IN DD-MMM-YYYY (i.e. 21-Feb-2018) FORMAT BY DEFAULT OR CUSTOMIZED .

When you download Firefox in your language, you should get the date format you're looking for :

https://www.mozilla.org/firefox/all/

You could also check the date/region settings in Windows Control Panel.
