My email was originally set up with Brighthouse which was acquired by Spectrum. My email address has a cfl.rr.com extension. Because of a hard disk problem, I had to reload Thunderbird. Spectrum is still maintaining the old Brighthouse accounts but support is extremely limited. I can now get into my account in Spectrum's email and can send and receive email there. I had to use a password I set up for Spectrum to do that. But Thunderbird will not recognize my cfl.rr.com account. I can import that account into Outlook and Gmail, but not Thunderbird. It appears to me that Thunderbird is looking for a password that Outlook and Gmail don't require. If I had an old Thunderbird or cfl.rr.com password I have lost it. I prefer Thunderbird, and I need to get my address book and history files back. I have just set up a new email account in Gmail and imported it into Thunderbird. Is there a way I can I recover my old address book and history files? I do have all the old Thunderbird files that I backed up before I had to reload Thunderbird.
