# Stop Thunderbird from automatically hyperlinking on send

Uppity Thunderbird has decided it's smarter than me. When sending a message, it automatically converts anything that looks like a URL to a hyperlink, even if I made sure it was not a hyperlink in the editor.

Besides being annoying, the automatic link insertion causes Thunderbird to send the message as HTML when it would otherwise be sent as plain text.

How can I show it who's boss?

From mozillaZine (Mozilla Wiki):

It is possible to take some steps to suppress automatically-generated links, but you cannot completely suppress them.

Sending messages

When you write an HTML message, you can suppress automatically-generated links.
Select the text that Thunderbird normally linkifies.
Choose Insert – HTML... In the HTML editor, type anchor tags around the text.
For example, if you type this but you do not want Thunderbird to linkify it:
someone@example.org
In the HTML editor, change it to:
<a>someone@example.org</a>
If there is already an anchor tag with attributes (class and href, typically), then remove the attributes to leave the tag looking like the example above.
