We use Mozilla at my work and are happy with it. In Denmark, both private individuals and companies have a security key called MIT ID ( My Id ) So we can log in to all public adminsrative sites. It is very important. After your last update it doesn't work. I am getting an error, and have spoken to Support and they say it is an error in your update. It has now been a week and the error has not been made. Which forces us to use a different browser, which I'd rather not. The Site with the error is https://nemlog-in.mitid.dk/login.aspx/mitid
