How To Edit Any Website Live

First let me make perfectly clear, you're only editing the site on your computer, as you see it. The changes are not permanent and don't have any adverse effects on the original site or its server.

However, one of the things I do often is save pages with tutorials on how to fix my vehicles or other random things. It's a huge pain in the ass to view the page source and then edit the html after you've saved a page. So... there's got to be a better way...

javascript:document.body.contentEditable='true'; document.designMode='on'; void 0

Copy the above line and paste it into your browsers address bar after visiting any site you want to edit. Now you can change text, delete images or blocks of ads, or just about anything you want. Then right click on a empty area and choose "Save Page As..." and the changes you've made will save.
