I just downloaded the new Thunderbird 78.2.2 but I cannot see how to import downloaded .mbox files (which were downloaded from Gmail). There is no Import/Export option under "Tools",only an "Import" option which then allows only to choose between "Becky!InternetMail"and "Outlook".I am very confused.I seem to remember using an older version 3years ago and could just copy the files manually intothe App Data folder but this stratgey does not work. Could someone pleasehelp? For info I amusing Windows10

Chosen solution

Open your Thunderbird profile folder, QUIT Thundebird and copy the mbox file to Mail > Local Folders. Remove the .mbox extension, it's not needed, then launch Thunderbird. You will find the messages under the Local Folders account.

Hi there, Apologies for my ignorance if this has already been covered, but I'm trying to solve the problem of importing my massive .mbox file into TB. Have read through the answers above but don't think anything covers this. I've done all the add ons and various recommended methods, but every time I get to my LaCie drive where my file is saved, TB crashes. If I go the other way, through account settings - message storage - local directory - browse, I'm unable to select my .mbox folder to upload (it's faint grey). Have taken screen grabs to explain where I get stuck. Cheers

Remove the .mbox extension from the file, then right-click Local Folders in TB, ImportExportTools NG/Import mbox file, select the mbox file All mail in...-003. You can't import an mbox file into an IMAP folder.
