I use the med advisor website to order medications. I have done this for many years. I started using Firefox last year and at first it worked fine. At one point, I think it was after an update, I could no longer Login to their site. I could bring up the Login page but it refused to let me enter my details, just the spinning circle. Now I can still get to their home page but it wont even load their login page. I can still use other browsers to login, so I am not inconvenienced. Still I am wondering why this is the case. I have no problems with Login to any other website, just this one.
