Chrome, Firefox, IE browser plugin to reload CSS without reloading the page

When developing and adjusting the CSS, a methodology is using firebug to directly edit the styles and then re-apply the change on the real file with the editor.
In other cases, it’s more practical to change the CSS directly, but reloading the full page is a bit time consuming.

Here is a trick to reload only the CSS. There are browser extensions for it, but at the time of writing, none of existing ones works as expected, at least on chrome.
So, I simply solved by creating a browser tool-bar link that reloads the CSS without reloading the full page, with one-line of JavaScript.

From your browser toolbar: right click and select the option to add a new URL (“Add Page” on Chrome)
name: “Reload CSS”
url: the following script

Or just drag this into the toolbar Reload CSS
