I saw this question already answered, but I am unable to find it.

If I upgrade from Firefox 55 to 56, package of FF 56 gets downloaded. What I need to do in apt to download only modified files in FF 56 package rather downloading whole FF 56 package?

Does doing an update downloads whole package too?

You are looking for debdelta:

To speed up the download of updates debdelta is added as a optional way to get package updates. [1]

man debdelta-upgrade [2]

   This program is designed to download changes (deltas) that may be  used
   to  apt-get upgrade all listed packages, and apply them.  If no package
   is listed in the command line, then it will  apply  to  all  upgradable
   packages. See debdelta(1) for more details on the delta files.

Usage after installation : (from here)

sudo apt-get update
sudo debdelta-upgrade
sudo apt-get upgrade
