Deleting standard browser

Question

Is there any difference between this command:
apt-get purge firefox

and these 2 commands:

sudo apt-get remove firefox && sudo apt-get autoremove

Answer 1

sudo apt-get remove firefox just uninstalls Firefox.

sudo apt-get purge firefox also deletes configuration files.

sudo apt-get autoremove removes packages that were automatically installed to satisfy dependencies for some package and that are no longer needed.
