[qubes-users] split firefox & thunderbird credentials?

I was wondering if the awesome split-ssh and split-gpg family could be
extended by a split-mozilla brother, that outsources passwords to vault
without exposing them? The lack of such a feature obliges me *not* to
save them within the two apps, which is a terrible pain, of corse ....

thanks in advance
