One of our suppliers has a valid certificate, but Firefox seems to decide for itself if one is valid or not. This is a blocking(!) issue for our company, since the site affected is one of our main suppliers! The supplier verified it, but certificates from GlobalSign are rejected. There is _no way_ around this. Even a manual import is blocked as Firefox declares the certificate invalid. I cannot add an exception since Firefox decides on that specific screen that the certificate is valid all of a sudden, but still keeps blocking(!) the page. Do I really have to install _any_ other browser to access our supplier? Anyone from the FireFox team to comment on this?
