Guto Utils is a Chrome extension developed by augusto.prodohl.neto. It falls under the category of Browsers and specifically the subcategory of Add-ons & Tools. This free extension focuses on removing notifications and potentially much more.

The main functionality of Guto Utils is to search for all notification elements present in the DOM. These notifications are identified by the HTML tag with the id 'FC_Notification'. Once a notification is found within the HTML tag, the extension simulates a click using the '.click()' method. This action removes the notifications and marks them as read, preventing them from reappearing when the page is reloaded.
