<!-- version: 1.2 -->

![A Screenshot][1]

To help people not accidentally delete them, especially the short ones. <br/>
(Also see [the cause to get them removed permanentely][2])

Sorry to not provide a file for download but i am sure you will manage somehow, adjust includes and exlcudes as needed:

<!-- language: javascript -->

    // ==UserScript==
    // @name           Remove Favourite-Tag-Delete-Buttons
    // @namespace      stackoverflow
    // @include        *stackoverflow.com*
    // @exclude        *stackoverflow.com/users/preferences/*
    // ==/UserScript==
    
    (function ()
    {
    	var cancelWaiting = false;
    	jq_wait();
    
    	function jq_wait()
    	{
    		if (typeof unsafeWindow.jQuery == 'undefined')
    		{
    			window.setTimeout(jq_wait, 100);
    		} else
    		{
    			$ = unsafeWindow.jQuery;
    			window.setTimeout(function () { cancelWaiting = true; }, 5000);
    			$(document).ready(tag_wait);
    		}
    	}
    
    	function tag_wait()
    	{
    		var items = $("#interesting-tags .delete-tag");
    		if (items.length == 0)
    		{
    			if (cancelWaiting) return;
    			window.setTimeout(tag_wait, 10);
    		} else
    		{
    			items.remove();
    		}
    	}
    })();

**Edits:**

 - Selector also matched the delete buttons on comments, which was not wanted.
 - Added @exclude exception for the preferences page
