lost emails in TB _ Answered here https://support.mozilla.org/en-US/questions/1307885 Thank you

Greetings and Felicitations, Foolishly and clearly in a fog, when I opened TB on June 24, I accidentally created another email account. I thought my ISP was asking me to log in again with addy and password. In short, when I went into TB, All my emails were gone, but All my addresses were there. Profile manager shows only one (default) So, inside "Mail", it appears I duplicated the folders. On June 20 I show Local Folders, pop.mail.yahoo.com On June 24 ( when I had my brain fart ), I show Local Folders -1 and pop.mail.yahoo-1.com The pop.mail.yahoo.com holds about 1.17 GB, therefore I think - Hope - All my emails are there. Inside pop.mail.yahoo.com there is a " Inbox " file 876,580 KB and some other things, including " Trash " file 321,504 KB - I never clear trash. I thought that if I delete the dups ( -1 ), then restart TB the original June 20 info - Maybe - will come back. But, since I am now fearful to do Anything else, Kindly tell me how do I put " Inbox " aka Emails - back in TB ?? I have read many support and replies, but none seem to address my issue. Thank you in advance for your time and advice. Cheers, Fabio
