Not sure where this goes. Feel free to move if needed… 
It’s pretty common knowledge that both the Developer Toolbar and Firebug allow you edit the CSS of any page you can view. Problem is, the edits are not persistent between page-view sessions. So, you refresh the page, you lose your changes.
Does anybody know of a FF3 add-on that allows a person to edit CSS for a page and persistently display the page with those edits until you chose to undo them? If there’s no plug-in: Does anybody know of a way to do this at all?
The person with a good working solution get’s free high-fives for LIFE.
Thanks!
