How to get rid of mozilla-browser?

[Jérôme Marant <jerome.marant@fr.thalesgroup.com>]

Hi,

  A recent installation of mozilla-browser failed on my system.
  It seems that it squashed its own alternative file.

  As a consequence, I can:
  - neither purge the package: dpkg tells me that the package is
  in an unconsistent state, and recommends to reinstall the package.
  - neither reinstall a new version since update-alternatives
  is failing on the squashed alternative file.

  How can I resolve the problem?
  
  Would feeding the alternative file with consistent information
  be a solution? If so, can a mozilla user show me its content?

  Thanks in advance.

  Cheers,
