Just wondering what is meant by "Weekly users" in Chrome Webstore? Is it the number of users who have clicked on the popup? Or does it also count if the users are just browsing while the Content Script is at work? What happens if an extension uses both content script and popup?
According to Joe Marini (lead Developer relations for Chrome apps/extensions/CWS):
The number [of weekly users] you see in the Chrome Web Store is the amount of users whose Chrome browser has checked for an update of your app within the last week. It is not the number of people who have installed your item.
