I am trying to login to my fb account through Opera, but it responds as an incorrect password. There isn't any chance that the password is incorrect, or my username, because both are stored in my computer and in opera's browsing password manager, since 3 years. I've been using this browser and logging in and out of my facebook account, every day.
In addition to this, I can login just fine, through other browsers, e.g firefox and chrome.
What is the problem?
