RE: Here's the link I used/followed: https://accounts.firefox.com/settings?context=fx_desktop_v3&entrypoint=fxa_app_menu&uid=084f536fe69f47beb7e1b579305416e1&email=johnspitters%40familynation.com This link goes to your Firefox account. I asked for the link to the instructions you were following when you said "8. In following the online instructions to restore the profile that I removed, I was unsuccessful in restoring it."

I am trying to answer the question you started with - restore default profile. You keep adding multiple responses asking new questions which means that following the process is getting confusing. Please focus on one thing at a time. That said, I am going to mention that you have another option - as you use IMAP you may recover by reconnecting Thunderbird to your original email account. Before you make that decision you need to log in to the webmail account online and check carefully that everything you had in Thunderbird is there - folders, address book contacts, emails. It should be, except possibly address book contacts and anything you saved in Local Folders. Logging in to webmail also confirms you are using the correct password, which you will use when setting up the account in Thunderbird. You may find that most of it is there and can decide whether you can recreate or live without missing addresses for example. Note that if you do reconnect without checking and then you need to recover the profile anyway, that will get you no further than you are now and may make things worse so think carefully before deciding. Once you have checked the online email account has everything you need, post back here to say whether you want to continue recovering the profile from backup, or have succeeded in reconnecting with IMAP.
