My sign in was “blocked for security reasons” on Firefox Accounts. There is no confirmation email. Not in spam, not anywhere. I'm trying to log in from another windows laptop (having no problem at home with it on my desktop and at work on my mcabook), for the second time in 1 month, and just can't. Also, please note, that saying just "blocked for security reasons" on the sign in page is a very, very bad UX practice. At least "a confirmation link was sent to your email" would be smth. Why on earth do I have to search forums to get your machine-like fact of failure decrypted? Have you designed this browser for humans? The good UX practice is to suggest a solution, not only state that smth went wrong. Anyways, if there exists a way to sync my account - this is the last shot I'm giving here, cause it just drives me nuts and I'm going in circles.
