Forum der Gemeinschaft Firefox

This has happened several times in the last 4 months or so, it had never happened prior to that and I've used Firefox for years. It now occurs when I open Firefox after my computer has either been shutdown, or the computer does a restart. I am signed in to my Mozilla account.

My Mozilla account has been disconnected. When I try to sign in, I enter my email and password, and am then prompted to enter a confirmation code that reportedly was emailed to me. The problem is that no such email arrives. Without that access code, I cannot log in, and syncing does not work. This is not a problem with my spam filter, because that filter is turned off, and I have no difficulty with receiving emails from other senders. How can I either get that access code sent to me, or get logged in without it?

I HAVE FINISHED SET-UP BUT I AM STILL BEING PROMPTED TO FINISH, WHY FIREFOX IS MY DEFUALT BROWSER IHAVE IMPORTEDTED SETTINGS AND MY SYNC IS COMPLETE UNDER MY PROFILE

Has Firefox instituted a security setting that is interfering with commerce-related sites? Suddenly I can't log in to my credit union (gets stuck on "authentication" step), amazon.com (endless "transferring data" message during login attempt), and mutual fund sites (similar to amazon.com experience). These all are related to money/commerce. I've turned off Firefox's popup blocking and even explicitly allowed cookies for the sites. I did a Refresh to get rid of extensions that might be causing problems (even though there wasn't a problem a week ago on these sites). I've tried Firefox on a second computer for the credit union site and got the same behavior. Chrome has no problem with these logins, by the way.
