Firefox account synch locked
I know that this seems to be an hot topic for questions, but after read some other messages I am confused on hot to proceed. This is my problem:
On a fresh installation of an Operating System on my laptop I tried to enable the firefox synch functions. After inser the password I was waiting for the pin code on my mail to certify my identity. This mail returned (I don't know why) and now my synch functions are locked. I am able to log in with my account: <email@example.com> but I am not able to start synch. How can I solve this issue?
