The Easiest solution for saving Changes in CSS is to install the “Firebug” Addon Firediff
After you install it and you restart Firefox when you open Firebug you will find a New Tab Changes that will serve to Inspect and Save changes made on your CSS file.
- To Inspect the Changes you made:
Changes > Change Log
- To Save your Changes:
- Right click Inside the Change Log Area
- Select “Save Snapshot“
