Firefox and its “about:config” feature is well documented. It allows you a peek into the features of the browser and set some for yourself. Chrome has its own version and you can access it by typing – chrome:about in the Omnibox (address bar). Though, it is meant for programmers and debuggers, you can take a look for curiosity’s sake.
Some of the commands available are useful – for example, if you want to check your browser’s history [chrome://history], all the extensions that are installed [chrome://extensions], or a detailed examination of the memory usage [chrome://memory].
An interesting feature is chrome://flags. It takes you to a page full of experimental Chrome features.
But heed the warning which says – “Careful, these experiments may bite.” These experimental features are unofficial, so go through them and use them at your own risk. This tip is meant for awareness about an interesting internal feature of Chrome.
