For some reason Firefox Containers with Cookie AutoDelete messes up with Twitter and I cannot login to Twitter. After entering user/pass I expect 2FA screen but I'm redirected to `https://twitter.com/login/error?username_or_email=...` url where I have to enter my credentials again. I'm not sure if I'm the only one.

I don't use 2FA with Twitter, but I have no issues logging in with Containers and Cookie AutoDelete. Just a data point that something else may be amiss on your end. Disabling other extensions and trying it could possibly help narrow down on the cause.
