Or you just accidentally typed your password into the wrong site, perhaps via phishing? Believing you weren't/couldn't be phished is a great way to get phished

  No, this is not possible. This password was generated by Firefox and apart from the test earlier to see whether or not it was changed I have never used it elsewhere much less copied it. It would have to be a session hijack or something like that.
