Hello,
I had the problem related in bug n°294175 with the package mozilla-firefox-locale-fr-fr and mozilla-firefox-eu.
The solution proposed to add the file defaults.ini wasn't accurate in my configuration (debian mozilla-firefox 1.0+dfsg.1-6).
Furthermore, it prevented me to use firefox (uninstall/install of mozilla-firefox and impossible to configure firefox after the aptitude install).
The only solution I found to remove the packages was apt-get remove --purge mozilla-firefox* , a bit violent, isn't it ?
If you have the solution to prevent this bug with defaults.ini ... (when I create this file, and I try to uninstall the packages mozilla-firefox-fr-fr and mozilla-firefox-eu , I still have the error message :
Updating mozilla-firefox chrome registry...E: /usr/lib/mozilla-firefox/extensions/installed-extensions.txt still present. Registration might have gone wrong.
mv: ne peut évaluer `/usr/lib/mozilla-firefox/defaults.ini': Aucun fichier ou répertoire de ce type
dpkg : erreur de traitement de mozilla-firefox-locale-eu (--remove) :
le sous-processus post-removal script a retourné une erreur de sortie d'état 1
And then, the file defaults.ini disappears again ...
