I can't access my thunderbird gmx account because it won't accept my password. This problem (I've been trying for a week now to find the solution) began when I used my laptop from a different location (that may or may not be relevant). My password is correct but I am simply told to retry it. So I can't access my gmx emails in Thunderbird. (I can access them by going to the gmx site but that is very laborious and not what I want to do.)
