Please note that sharing a cookie between different top-level-domains is
not possible at all. When switching languages I assume you are also
switching top level domains (i.e. from the .de to the .fr TLD). You will
have to manipulate the language switching links to add some information
in order to transfer the session from one domain to the other.

I am not aware of any extension that does that, but it seems possible to
do and might be an useful asset to the TYPO3 Community if you manage to
get it done (or sponsor someone to do it), as this problem pops up from
time to time. :)
