Classic Sidebar

About this add-on

Restores the multi-panel sidebar from Netscape Navigator 6.x-7.x, Mozilla Application Suite and SeaMonkey. It is a direct port of the source codes from SeaMonkey, with some modified to work in Pale Moon. As a result, the license is MPL-2.0.

Also, it exposes window.sidebar.addPanel and window.sidebar.addPersistentPanel functions to the web pages just like in Netscape Navigator and SeaMonkey.

To customize the sidebar's appearance, you can use a complete theme that has sidebar.css present in chrome/browser/sidebar/ directory.

I also fixed a bug that were present in SeaMonkey where panel customization URL being ignored. Also I have added window.sidebar.addRawPanel and window.sidebar.addPersistentRawPanel functions that accepts raw HTML codes for the panel and customization dialog rather then URLs.
