Hello. I have a web design annoyance. With my workflow, I modify a web page, upload it with the click of a button (to a remote "preview" server), and then "refresh" the page in my browser to see the difference. I often need to see extremely subtle tweaks, like a pic moving 2 pixels, etc.
But when I do this, instead of an instantaneous refresh, the browser gives me a BLANK SCREEN for a .5 - 1 second, as it reloads and re-renders the new page. My mind cannot memorize what the old page looked like, not in detail. To make a good comparison, the page would have to switch instantaneously, or much faster.
So, does anyone know of an add-on, or a method, for Firefox or Chrome, which will do this? I guess it would "hold the old page on the screen until the moment the new page is rendered".
