I recently developed a free chrome extension (work in progress) in order to beautify my var dumps with no libraries, no pre tags and no installation to each and every app. All done with JavaScript and regEx. All you have to do is install the extension and your good to go. I am working on a Firefox version as well. Here is the GitHub page. I hope to have it available on the chrome and firefox webstores soon!
