Blocking files in the signature

Mozilla Thunderbird gives me this error message: "Thunderbird has blocked the file from being added to this message. By unblocking it, you can add it to your message for sending."

Even after unblocking, it won't add the file (company logo) to my signature. I have the path to the file listed in the signature settings.

How can I set to cancel the check of files added to the signature?
