Recently, I upgraded my TB to 128.0.1esr (64 bit). After the upgrading, I encountered the following problems. (I am using IMAP to communicate with the email accounts. ) 1) For some new email in the inbox, the email content could not be show, ie the email body is blank. 2) Those read email but still kept in inbox and other folders were not downloaded. Please advise how to fix the problems. Thousand Thanks cheers, Karl
