38.3.0 installed a month ago. This am, Tbird says messages are being downloaded from server, but never show up in Inbox. Can send emails. Error console starts with (E=error, W=warning, M=Message): M Could not read chrome manifest file. W Use of Mutation Events is deprecated. E TypeError: tab is undefined, in tabmail.xml M SHA-1 strength recommendation (2 of these) M Unknown property 'xxx'. Declaration dropped. (5 of these about mozorg.cdn.mozilla.net/.../start-bundle-xxxx.css file) E downloadable font: kern: Too large subtable (2 of these about start-bundle-xxxx.css file) .... Full scan of Windows 7 system was OK. For time being, I've stopped Tbird from checking for new messages at startup or every 5 mins, or auto downloading new msgs.

When you look in the activity manager, what is showing regarding the status of the download?

Problem was only 350 Mb of space for the cache (my son guessed at this). After bumping it to 500 Mb and removing a couple thousand messages in the Sent and Trash folders, the new messages came into the Inbox.

I still get 11 messages in the Error Console every time I start up Thunderbird: 3 Errors, 7 Warnings, 1 Info. If interested, I can give them to you.

Solution was to bump the size of the cache, delete thousands of old messages in multiple folders, and then Compact those folders.

To really fix this, does Thunderbird need to improve its handling of the exception that signals it has run out of virtual memory?

BTW: If a user hasn't set up a support account, and has an email problem like this that prevents messages from getting into the Inbox, then the problem won't be posted because the user can't acknowledge the email you send to confirm the email address associated with the new account. A nasty Catch-22.
