-// An interim workaround for 101131 - Bookmarks Toolbar button nonfunctional.
-// This simply checks to see if the bookmark menu is empty (aside from static
-// items) when it is opened and if it is, prompts a rebuild. 
-// The best fix for this is more time consuming, and relies on document
-// <template>s without content (referencing a remote <template/> by id) 
-// be noted as 'waiting' for a template to load from somewhere. When the 
-// ::Merge function in nsXULDocument is called and a template node inserted, 
-// the id of the template to be inserted is looked up in the map of waiting
-// references, and then the template builder hooked up.
