Extract and Download Multiple Attachments At Once

I was searching for a way to extract and download multiple attachments at once and came across a thunderbird plugin that allows you to do this.

Just select the messages containing the attachments you want to extract and select 'Extract Attachments' and this extension does the rest. No more having to go through each message to extract the attachments!
Check out the settings dialog for the different options.

For downloads and further information, check addon's page.
