Does anyone know of an extension or add on for Chrome or Firefox that I can edit html on a live website, that will load the changes I've made upon refreshing? I currently can make the changes via right click >> inspect but the moment you refresh it goes back to the original page. I'm hoping to use it to show a live view of a websites before and after without having to save a copy of the page to my desktop.
Someone has mentioned Greasemonkey or Tampermonkey but I wouldn't even begin to know how to figure that out. If you know how to use either some advice on them would be peachy!
