I've also experienced this bug and it's a show-stopper for either upgrading or requires changing distro, and makes Ubuntu unusable for many enterprises. We don't accept user/password combination so a fallback to that from Kerberos isn't possible and moving the ccache isn't possible or supported either.
Also, since the snap:ification, the browser doesn't use system certificates store anymore, which makes certificates break for all websites when for example intermediate certs are rotated in the system store, which is a security issue since users will be taught to accept expired certificates.
