I ran into this, too, when upgrading iceweasel (which pulled in
firefox-esr) and installing firefox in the same aptitude run:

Preparing to unpack .../firefox-esr_45.0esr-1_amd64.deb ...
Removing 'diversion of /usr/bin/firefox to /usr/bin/firefox.real by iceweasel'
dpkg-divert: error: rename involves overwriting '/usr/bin/firefox' with
  different file '/usr/bin/firefox.real', not allowed
dpkg: error processing archive /var/cache/apt/archives/firefox-esr_45.0esr-1_amd64.deb (--unpack):
 subprocess new pre-installation script returned error exit status 2
Selecting previously unselected package firefox-esr-l10n-de.

Please don't! And if it's necessary policy-wise, please make firefox
and firefox-esr co-installable as xulrunner-* was in the past. (And
then maybe use update-alternatives for /usr/bin/firefox -- that would
have avoided that issue, too.)

I'd be great to be able to fall-back to firefox-esr if firefox once
again broke compatibility for XUL applications or plugins while still
being able to to use the current version firefox without them (or to
develop a fix while still being able to use them).
