HTML5 notifications are great for some applications, but they require the user to grant permission before receiving notifications. It solves a different problem than the favicon notification technique.
Seems to not work if you use a .png instead of a .ico for your favicon.
Both PNGs and ICOs should definitely work. Unless you specify a favicon in the function call, it will look for the one specified in your head. If one is not specified in your head it will use the default favicon location (/favicon.ico).
This was inspired by the favicon notifications for gmail. I'll add an exception for clients without canvas, but it should be as fully compatible as is possible.
Is this working for anyone? I don't see any favicon changes in Chrome or Safari.
Safari doesn't work for me, but Chrome does.
It works for me in Chrome for Mac.
It should work in Chrome 6 and above and Firefox 2 and above. There is no support for modifying favicons in other browsers client-side.
Weird – I'm using Chrome 14 and Safari 5 and don't see it. Firefox works though.
W4M in both Firefox (nightly) and Chrome in Ubuntu. Really cool, I can see lots of uses for this.
Do you have an alternative URL: github appears to be down right now.
