Apologies for replying twice to the same enquiry, but I might be able to
provide slightly more information.

Iceweasel and Firefox are not independent packages in Jessie. If you do
"apt-cache show iceweasel" you get the following:

Package: iceweasel
Source: firefox-esr
Version: 60.6.2esr-1~deb8u1
Installed-Size: 249
Maintainer: Maintainers of Mozilla-related packages
Architecture: all
Depends: firefox-esr
Description-en: Web browser based on Firefox - Transitional package
This is a transitional package, it can be safely removed.

Priority: optional

Note that it depends on firefox-esr. If you install Iceweasel, what you
actually get is Firefox.

All you're doing by explicitly installing firefox-esr is setting it to
being manually installed rather than pulled in by implication.

The firefox-esr package includes both firefox and firefox-esr
executables so I'm not sure why firefox-esr is not working for you.

The iceweasel package seems to include just a linking command, so you
can still invoke firefox as iceweasel.

Your assumption is wrong - they are not separate.

As has been asked several times, why? What do you think it will achieve?

A slightly odd way of putting it. The reality is that if you ask to
install iceweasel, what is actually installed is firefox-esr, plus some
linking bits so you can invoke it as "iceweasel".

The reason you can't install firefox-esr after installing iceweasel is
that it is already installed. Under the skin they are the same program.
