Countdown is a free Chrome extension developed by kikoogay that adds a customizable countdown to the New Tab Page. With this extension, you can watch the hearts fill up as you get closer to the awaited event you've been eagerly anticipating for months. The countdown feature adds an element of excitement and anticipation to your browsing experience.

One important thing to note is that Countdown replaces the New Tab Page, as it is currently not possible to add anything to the page without replacing it. However, despite replacing the page, Countdown still displays your most visited pages. Additionally, you have the flexibility to customize the range used in the history and the number of thumbnails displayed, even exceeding the default limit of 8 in Chrome.

Overall, Countdown is a useful and visually appealing extension for Chrome users who enjoy having a customizable countdown on their New Tab Page.
