Tinycon allows the addition of alert bubbles and changing the favicon image. Tinycon gracefully falls back to a number in title approach for browers that don’t support canvas or dynamic favicons.

Alerts in the favicon allow users to pin a tab and easily see if their attention is needed. You can look up and check out the favicon on the example page to see the library in action on chrome and firefox.

Requirements: Canvas Supported Browsers
