[Ext] AttachmentCount

The AttachmentCount extension adds an optional column to the Thunderbird thread pane showing the number of attachments in a message. Features include:

  • Shows the count or an icon for a single attachment
  • Indicates whether all attachments are detached or deleted
  • Tooltip preview for text attachments (and for binary attachments if really desired)
  • No need to select a message to get an accurate indicator
