[pag77]

From time to time in the Bookmarks disappear icons for websites, for example, after the synchronization of bookmarks across Firefox-syncing
This solution will restore icons - each time you open bookmarks will be checked for the presence of an icon of a particular site and then try to recover it.

Install:

1. Install Menu Wizard, if it is not already in your browser
2. Open the settings Menu Wizard: "Tools > Menu Wizard", "Add-ons > Menu Wizard > Settings" or type in the address bar about:config-menu
3. Open the menu "Menu Bar"
4. Open the properties in the "Bookmarks"
   
5. In the "Command > onPopupShowing", insert this code:

   Code: Select all

   this.check_icons = function(event) {
   	var menu_popup = event.target;
   	var menu_items = menu_popup.childNodes;
   	for (var i=0; i<menu_items.length; i++) {
   		var menu = menu_items[i];
   		if ((menu.localName == 'menuitem') && (menu._placesNode)) {
   			var place = menu._placesNode;
   			if ((place.icon == '') && (/^https?\:\/\//.test(place.uri))) {
   				this.get_icon_html(place.uri);
   			}
   		}
   	}
   }
   this.get_icon = function(page_url) {
   	var favicon_url = /^https?\:\/\/[^\/]+/i.exec(page_url);
   	if (! favicon_url) { return; }
   
   	favicon_url = favicon_url[0] + '/favicon.ico';
   
   	var req = new XMLHttpRequest();
   	var self = this;
   	req.onreadystatechange = function () {
   		if (req.readyState == 4) {
   			if (req.status == 200) {
   				self.set_icon(page_url, favicon_url);
   			}
   		}
   	};
   
   	req.open("GET", favicon_url, true);
   	req.send(null);
   }
   this.get_icon_html = function(page_url) {
   	var req = new XMLHttpRequest();
   	var self = this;
   	req.onreadystatechange = function () {
   		if (req.readyState == 4) {
   			if (req.status == 200) {
   				var favicon_url = self.icon_parse_html(page_url, req.responseText);
   				if (favicon_url) {
   					self.set_icon(page_url, favicon_url);
   				} else {
   					self.get_icon(page_url);
   				}
   			} else {

   	}
   	while ((link = RegEx_link.exec(head)) !== null) {
   		if (RegEx_rel_sicon.test(link) === true) {
   			href = RegEx_href.exec(link);
   			if (href !== null) {
   				FavIconURL = href[1];
   				break;
   			}
   		}
   		RegEx_link.lastIndex;
   	}
   
   	RegEx_link.lastIndex = 0;
   	if (FavIconURL === "") {
   		while ((link = RegEx_link.exec(head)) !== null) {

   }
   this.setAttribute("onpopupshown", "this.check_icons(event)");
   

6. Click "Apply"

PS:
For testing the code, you can use an addon to remove icons: Delete Bookmark Icons
A small piece of code was taken from the addon: FavIcon Reloader
