Try to add a type attribute to the link element.

<link rel="shortcut icon" href="demos/images/favicon.ico" type="image/x-icon">

If you have the favicon.ico image file in the root directory of the website that "shortcut icon" code isn't needed.

Adding type="image/x-icon" didn't change anything

Moving the favicon.ico to the same folder as the html file doesn't work either. If you meant the root of the website, I have no way to do that. And this doesn't explain why the css3 demo page does show the favicon while the others don't.

Reload web page(s) and bypass the cache to refresh possibly outdated or corrupted files.

• Press and hold Shift and left-click the Reload button.
• Press "Ctrl + F5" or press "Ctrl + Shift + R" (Windows,Linux)
• Press "Cmd + Shift + R" (MAC)

It works for me though if I run this code in the Scratchpad (Shift+F4);

N=document.createElement("link");
N.setAttribute("href", "demos/images/favicon.ico");
N.setAttribute("rel", "shortcut icon");
N.setAttribute("type", "image/x-icon");
document.head.appendChild(N);

Hmm, that is interesting that adding the link with javascript does work, but having the type added to the link still doesn't seem to work. Helpful, but not really the answer I need. I'd like to get it to work without using javascript.

I'm not seeing that attribute in the current website code, so I can't test this.

Ok, I've updated all of the demo pages. Still no luck =(

The favicon.ico file doesn't seem to be working as a favcion.

Try to recreate or re-save the image file and upload that image to the server.

Hmm, still no luck. I used this photoshop plugin to save the ico file (using Windows 7). Maybe I need to use something else.

It works if I disable JavaScript.
Looks that it is caused by JavaScript that runs on the page and that modifies the URL (hash).

Ahhh, I see, now to figure out how to stop it. Thanks for the help!

I found this solution:
