We have shared Iconic Firefox Menu, Movable Firefox Button and Firefox 4 UI Fixer add-ons in past which help in customizing appearance of new orange button in Mozilla Firefox 4.0 and later versions.
Today we are going to share 4 more excellent Firefox add-ons which allow you to customize the orange button and also help you in adding extra functionality to this new orange button.

App Button Clear
This add-on makes the orange button transparent.
App Button Remove
This add-on removes the orange button from titlebar.
App Button Color
This add-on allows you to change orange button's color.
App Button Close
You can add an extra action to the orange button using this add-on. You can close Firefox window by just double-clicking on the orange button.
Thanks to our reader "Greg" for sharing...
