How do I change Firefox bookmark toolbar icons?

My Firefox bookmark toolbar items change icons every now and then for apparently no reason, especially if a site is down. I get the DNS site's icons all over, on another case I have the Facebook icon on a TOTALLY irrelevant bookmark, so the question is: How can I change the icons on my bookmarks in the bookmark toolbar?


Favicon Picker 2 adds a UI for replacing bookmark icons. The extension is based on the the version posted in MozillaZine. It also features an increased icon size limit.

enter image description here


Point your bookmark at a local HTML document that immediately redirects to the desired destination. Link to a local favicon in the same directory.

You may need to restart your browser before the favicon will show up on the bookmark.

file:///[path]/example.html

<html>
<head>
    <meta http-equiv="refresh" content="0; url=http://www.example.com" />
    <link rel="shortcut icon" href="example.ico" type="image/x-icon" />
</head>
<body></body>
</html>

file:///[path]/example.ico


This solution suits my personal needs in Firefox 47.0. Note that the solution doesn't work so well where:

  • You need to create such bookmarks frequently.
  • You have disabled redirection as a security precaution.
  • The bookmark must point directly at the destination.
