emails with attachments are no longer being downloaded to the inbox from ATT's (yahoo). Logging in via the mail.yahoo.com webpage shows the emails in the inbox, but thunderbird does not download them. I changed the browser.cache.memory.max_entry_size to -1, and the browser.cache.memory.capacity to 400000, but that had no effect. I also downloaded the installer and re-installed (without removing first), and also had no effect. Any help would be appreciated. Thanks
