Things You Should Know About:
• Clippings for Thunderbird 6.0 is compatible with Thunderbird 78 only. It is not compatible with earlier versions of Thunderbird, nor is it compatible with current beta releases of Thunderbird.
• The option to show a prompt when pasting a clipping containing HTML tags into an HTML-formatted message is no longer available. If you had selected this option in previous versions, the clipping will now be automatically pasted as formatted text.
