Ways to clear HTML5 Local Storage files on Mac OS X

What exactly is HTML5 Local Storage?

HTML5 Local Storage is the data that web applications store locally within your browser. Web application data used to be stored in cookies, but that was before HTML5 came along. With HTML5 local storage, larger amounts of data can be stored locally (in the browser), and that data is more secure. The issue? This data is stored on your Mac, taking up extra space over time.

Unfortunately, there isn’t a go-to method of removing local storage manually (safely, that is). This is because some local data cannot be accurately identified via Finder. Doing so takes a bit more know-how or a Mac utility like CleanMyMac X to remove it correctly. But luckily, CleanMyMac X makes it incredibly easy.
