Edit any website with a line of Javascript code
Just copy and paste the code below into your web browser’s URL bar, and click enter on any site. I found that after you have edited the site, you can save it locally and it will be the state that you modified it to.
javascript:document.body.contentEditable=’true’; document.designMode=’on’; void 0
