Ah Google Chrome extensions, as long as you don’t go too crazy with the extensions they can be great tools. Take Wappalyzer as an example. This extension will give you a bunch of information about the webpage/site that you are visiting. What was the page built in: Drupal, WordPress, Wix, whatever Wappalyzer will tell you. It gives you a quick glance at how a page is built. After a while you start getting the hang of what pages are built with what platforms. Try it, you never know what you will learn.
