 Is this only a configuration change, such as
 security.ssl3.rsa_rc2_40_md5 = false?

 Such a change could be advertized in NEWS.Debian, with quick
 explanations on how to revert that on a system-wide or per-user basis.

 (I wonder if we shouldn't have a common postinst-snipset or a common
 config file to store such things and make the move at a single place.)

 Sample I'll ship in my next README.Debian upload:

Mozilla parameters
In some particular cases, you might need to setup the underlying Mozilla
components of Galeon.  This can be done via the .galeon/mozilla/galeon/user.js
file.  For example, to enable SSLv2 (which is disabled by default for security
reasons), insert the following JavaScript snipset:
    // SSLv2 is disabled by default because of security issues
    user_pref("security.enable_ssl2", true);

You can list other values by visiting the "about:config" page.
