Unfortunately, it will be a while before 1.11 migrates from experimental to sid to fix this. It's a new upstream version and it seems to be getting a fair bit of churn at the moment.
I expect this to be fixed in a week or two. Also, when you say firefox is not installable, you presumably mean that it's not installable if all of the following conditions are met: 1) you have both i386 and amd64 as current architectures 2) you attempt to install libkrb5-3 for both architectures possibly by installing libgtk for both architectures. Firefox itself shouldn't require multiarch as I understand it. I'm sure you realize this, but as a note for any users blocked by this issue: Also, for end users, although not so much for automated installations, you can simply grab the libkrb5-3 from security for both amd64 and i386. -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
