I've just added a new signature in Thunderbird and when I go to send a new message it has a bunch of red lines around the layout of the signature, probably because it's within a html table.
Now I know when I send the message the receiver won't see these lines, however it is still annoying and I would prefer to see the signature properly rather than it look like something you should only see when in "preview" mode or something.
Here is an example:
Is there any way to remove this red outline and get it to display the signature the same way it will be received?
