// Your code here...
var textbox = document.getElementsByClassName("ire-message-send")[0];
var textArea = document.createElement('textarea');
textArea.setAttribute('class', 'ire-message-send')
textArea.setAttribute('name', 'msgtext')
textArea.setAttribute('cols', '50')
textArea.setAttribute('rows', '6')
var text = textbox.value;
var parent = textbox.parentNode;
parent.replaceChild(textArea, textbox);
Solution 2: Manual change
You can open up your browser console right to the textbox by right clicking on the textbox, and selecting Inspect Element. Then, where it says <input change that to <textarea. Boom! You now have a textarea while you're at your computer to send the message from.
Hopefully this helps some of you. The Tampermonkey path is obviously the simpler solution if you use it, but the other way is fine if you need a one or two time fix.
