Thanks for reaching out Gabriel.  The Firefox Accounts service is
currently operating with tightened security rules due to an uptick in
suspicious login attempts.  Unfortunately this also increases the
likelihood of us blocking legitimate login attempts such as yours, if
they appear too similar to the suspicious traffic.

I can't suggest a workaround right now, but I'm hopeful that we can have
things back to (close to) normal in the next few days.

Longer term, we have a number of new security features in the pipeline
that will give us better alternatives to just outright blocking
requests.  For example, we will soon allow you to do an email
confirmation loop that verifies a login as legitimate, no matter how
"suspicious" the request may have seemed according to our operational
security rules.
