This extension, first, shows you a list of matches which are currently going on and their current status. You can choose which all matches you want to follow. Now you will get live desktop notifications of any major events (like 4s, 6s and Out) in any of the matches you are following. Clicking on the desktop notification will redirect you to the cricinfo scoreboard.
Post your feedback and let us know what you want to see in the future updates! Thanks.
