That is really strange ...

See, I have this alias on all my boxes:

alias auf='sudo aptitude update && sudo aptitude full-upgrade && sudo *apt-get

And I run auf when I get emails from apticron that updates are available.

Never had an issue with autoremove.

And rarely there has been any other issue, except when using PPAs that have
conflicting dependencies.

I need to research what really goes on with remove/autoremove/purge.

The way I understand it is that:

remove: uninstall the package but keep its files where they are.

purge: explicitly removes a package that you do not need, and its files.

In the both of the above cases, you will be prompted if it breaks
dependencies of other packages on your system.

autoremove: removes things that are superseded or no longer needed. These
are mostly specific versions of
linux-image packages that are installed via a meta package. When you
install v5, then v4, and v5 will be in
your grub menu, but v3 is no longer needed and should be autoremoved.

Other instances of autoremoving are rare.

Seems like "remove" ditches the program but leaves config files and

I am guessing that what happened is Firefox was your only browser, so
www-browser would resolve to it, and many
packages depend on www-browser.

When you removed (or purged) firefox, you removed www-browser, and then all
those other packages that
depended on it complained. You are usually prompted on what you want to do
(leave dependencies broken,
remove some more stuff, ...etc)
