I tried logging into addons.mozilla.org after changing my Firefox account’s primary email address and it returned a JSON response saying “Internal Server Error”. When I change the email back to the previous primary, login works again. There is no extension or anything blocking the login and attempting to log in from Chrome yields the same results. I also tried revoking the login in the “Devices & Apps” section and logging in again, without success.
I still have the same problem as T0ast. I’ve changed my primary email more than a week ago and amo login still doesn’t work : always that “Internal Server Error” response. If I switch back to the previous email, it works again.
I don’t know what to do : do I have to create another amo account with the new email or do I have to create another Firefox account with the old one ? Or something else ?
