I use a password manager. Many of the web-based services I subscribe to use my email address as my user name - this is quite common. When I am trying to login to one of these pages, your "Let Firefox hide your email address" message pops up over the selection box from my password manager. There doesn't seem to be an easy way to remove your message - which, in this context is totally inappropriate - but your message prevents me from logging in to my account when I need to choose between identities (example, work and personal). Can I turn these messages off? or can you add a simple "X" to the window so I can close it without that action being picked up by my password manager?
