Thunderbird 115.8.0

According to the release notes, the update to version 115.8.0 brings the innovation that the option has been added to display package dumps if OpenPGP fails during decryption. The update also includes the following bug fixes.

  • Thunderbird was slowed down considerably when opening e-mail files (.eml)
    The inbox view occasionally reverted to the default view after moving or deleting messages.
  • The size of collapsed folders in the folder window did not include the size of the subfolders.
  • When hovering over a folder, the subfolders are not always expanded.
    When switching to the subject area of a folder via the keyboard navigation, the top message was not focused.
  • When clicking on "Sent, unsent messages" in the context menu of the outbox in offline mode, the user was not prompted to go online.
  • Unified Toolbar buttons on the "Email" tab did not receive focus correctly.
  • Quick filter settings were not retained when the quick filter bar was disabled.
  • Quick filters were unusually slow.
  • OpenPGP key manager filtering did not work.
  • OpenPGP sometimes tried to decrypt a message with an incorrect key.
  • Autoconfiguration failed on servers that did not support OAuth2.
  • Opening different attachments with the same name in different messages could cause the attachment files to be merged.
  • Overflowing attachment list could not be scrolled.
  • Passwords disappeared from the password manager list after filters were applied and deleted.
  • Cookies in the cookie manager list disappeared after applying and then deleting filters.

The security vulnerabilities described here, some of which are classified as high, have been fixed. The system requirements for the various operating system versions (see here for more details):

  • Windows: Windows 7 or higher
  • Mac: Mac OS X 10.12 or higher
  • Linux: GTK+ 3.14 or higher

The free Thunderbird download is available here. Thanks to the reader for the hint.

Is there a bug in IMAP?

Addition: Mark Heitbrink just contacted me and wrote that he has the feeling that the new Thunderbird is constantly downloading IMAP messages. Here are his comments:


I have set up TB again as I have a new notebook. My TB won't stop downloading the messages, though I think it's just permanently checking them.

I have the feeling that it is worse with every network change and restart. I travel a lot and in the "new" network it takes forever until it thinks it's finished.

Then at some point it's finished and starts again with a different network.

Mark has already done some research, but thinks that the ideas about Thunderbird in the help and elsewhere on the net all refer to POP3 problems and deleting a file. Unfortunately, this does not apply to his scenario. He asks: Is there anybody who knows a solution?
