FAQ

Can an image be attached as a JPEG or a GIF?

Yes, set the preference clipboard.paste_image_type. Here's how.

Files have a number suffix (e.g. image-1.png) although I have only one file attached.

This can happen if Thunderbird was not shut down properly with an unsent message open. Solution: Delete old files from the system temp folder (defaults to %LocalAppData%\Temp on Windows).
