New Tab Countdown Updated

Fullstack Studios

New Tab Countdown replaces the default new tab with customizable countdowns. You can add or remove countdowns, and can select a time remaining format (in seconds, minutes, hours, days, or weeks) and a specified end date (day, week, month, year, or a custom date and description) for each countdown. NOTE: This extension updates a previously outdated one after the manifest v3 changes - https://chromewebstore.google.com/detail/new-tab-countdown/pbeiaielhjhfdpnonbbincehnanaehon
