I am on macOS Sierra trying to find the firefox version via command line using command below

/Applications/Firefox.app/Contents/MacOS/firefox -version

which prints out the version of firefox but i could see the firefox kind of pops up from system tray for a brief time.

Not sure whether it launches firefox and kills when we run the above command. Is there a way we can find the version of firefox with out actually launching ?

If you still have it, you can check the installer program.

You can check the applications.ini file in the Firefox installation folder.

Thanks cor-el for taking your time and replying on this. The applications.ini folder did have version number in it , does it get updated whenever the major/minor update of firefox happens.
