Форум спільноти Thunderbird

I am using Linux Mint and Thunderbird v140ESR.

I have searched the knowledgebase here to find out how to add an attachment to an email. All the screenshots are for the Windows version, even though I have selected my version from the selector on the RHS:

Any advice gratefully received.

Last week I saved the attachments of an email to a new folder in Documents. Today I received a new email with attachments. I saved these attachments to the same folder. To my surprise the old files (from last week) got a new timestamp. The date is today and the time is a couple of minutes after midnight. Any idea how this is possible? PS. I'm using Thunderbird on an Ubuntu machine.

I've noticed that if I attach a file to an outgoing message then use ctrl+enter to send the message, Thunderbird also opens the attachment. How can I prevent it from doing the latter?

Menu: Message>attachment>delete all

When delete all attachments for a message, when delete all attachments, auto move to the next message.

This behavior is annoying, usually I first delete all attachments and then reply but message position is in the next message.

This behavior is for example for version 140.7.1esr and 140.8.1esr.

102.15.1 work fine.
