I am using Google Chrome. On the first page I want to know how many emails have been sent to my Gmail account. For that reason I installed a Gmail extension. Now there is an icon, but it does not work. Many emails arrive, but the icon does not show.
The problem is with the extension itself. It's not working as it should and you need to replace it with something that actually works. Please use Checker Plus for Gmail because I can assure you it works properly since I am using it day-by-by on a regular basis.
