The recovery key for Firefox I saved a year ago won't work today. The Mozilla record of my secondary email address is corrupted and won't display, but when I try to add it the error is that the email address already exists. But it doesn't exist anywhere in the online account record data available to me! I need to enter new email addresses for both my primary and secondary firefox accounts. I'm almost 85 and feel resentful regarding the befuddlement of self service tech support that wastes so many hours on uncertain guessing about tech stuff I don't understand or know where to turn for resolution.
