Auto Hide Sidebar

The author has marked this style as obsolete.

Hides the Sidebar until the mouse contacts the left edge of the screen where it's hidden. Need to establish the width of your present Sidebar by using DOM Inspector. In the DOM location bar enter chrome://browser/content/browser.xul and click on inspect. Ignore the Session Manager by closing it (if it pops up). Click on window(plus sign) > stack(plus sign) > hbox(plus sign) > vbox and in the right panel select Object - DOM Node, there you will find the width of the sidebar. Subtract 1 from that number and enter that value as a negative number in place of the -215 in userChrome.css for #sidebar-box { margin-left: Removes vertical separator, search: label, search input box, closebutton, title text, scrollbar (scrollable with mousewheel) and adds 3D border. Also removes the Bookmarks or History item from the View > Sidebar > Menu popup, for which ever view is active. Tip: For access to widen the Sidebar, grab it from the 5px area just below the bottom toolbar (at the top left corner of the screen while in Fullscreen mode). See after screenshot.
**Updated to restore right click context menu**
