Firefox Password Update box is preventing me from logging into applications and programs, when I need to enter a NEW password, different from the one saved on Firefox already. The Firefox Password popup immediately stops me from entering the program. After I click on "update now" or "not now," Firefox box closes. BUT, the program password I entered (e.g. for Google, Twitter, etc) always defaults BACK to previous one saved on Firefox saved password, so it won't let me update to the NEW password. How can I stop it from reverting back to the OLD saved password, which is now invalid?
