  • Active users
    • In Chrome, the weekly active users is the amount of users whose Chrome browser has checked for an update within a week. This is not the number of installation. The users may not have interacted with the extension during that week. The extension may not even be enabled. This number is updated daily.
    • In Edge, the number is counted in a similar way as Chrome, but Edge updates the number weekly instead of daily.
    • In Firefox, the counting method is similar, but it is tracked as daily active users instead of weekly active users. That is, Firefox will only track for number of users within a day, not over the course of a week. This number is updated daily, and can fluctuate quite wildly, especially during weekends and holidays.
  • Extension vs. Add-ons
    • In Chrome, there are three types of items in Chrome Web Store: extensions, themes, and apps.
      • Extensions like Honey, uBlock Origin, Grammarly, etc. can run custom codes that enhances your browsing experience like blocking ads, modifying your web pages, changing your new tab page, etc.
      • Themes will simply change the look-and-feel of Chrome without the ability to run any code, so themes are generally safe to install.
      • Apps are deprecated. They were clickable apps in Chrome that will take you to a full screen web app with some extra permissions that can modify your browser. Now apps are no longer accepted in Chrome Web Store. Only a few of them still linger in Chrome Web Store.
    • In Edge and Firefox, extensions are also known as add-ons, though Firefox is also branding them as extensions. For all practical purposes, extensions and add-ons are the same.
