Hide Bookmarks menu left pane in FF3

Hi,
In FF2 you can hide the left panel bookmarks menu by sliding the bar to the left,i like to do the same thing in FF3 so i make a Google search and i found this code to add to your "userChrome.css "....


/* Allow sidebar to be closed completely using the slider */
#sidebar-box {
overflow-x: hidden !important;}
#sidebar {
min-width: 0px !important;
max-width: none !important;
overflow-x: hidden !important; }


I can't make it work, anybody can help me on that?

 

The All-in-one Sidebar extension might be a simplier route towards accomplishing what you seek.
