About a month ago my sign-in to three public libraries (all with URL containing sirsi.net) stopped working. I've tried this with both Firefox and Vivaldi (Chrome) browsers. The icon shows that their is a sign-in match but when I try to fill nothing happens. I've contacted Bitdefender support three times but I only get a generic response with suggestions that don't work. I don't see anyway to get their attention to this problem. It's pretty specific to a certain domain. I've tried adding it but that doesn't work.
