Hello,The "Periodically, every 10 minutes" option of the Message Filters does not work. It does not actually run every 10 minutes.Kindly fix this it's a very useful feature.

When attempting to deleted large number of selected emails, Thunderbird freezes for hours and nothing happens. Please fix this issue.

Play sound for incoming mails is selected but no sound is played. Even with "Play" button there is no sound. What is wrong?

When large number of emails are selected, deleting takes a very long time and application is not responding for long time before the items are finally deleted
