Toolbar button similar to Back/Forward buttons of firefox - xul

I am developing a Firefox addon. I need to create two buttons which exactly looks and operates like back and forward buttons. But the difference is I need to put my own icon inside them. I am completely blank. Any directions will be really helpful.

[Edit] I am asking for creating two buttons with the loo开发者_运维问答k and feel of back/forward button(Although there are two buttons, it seems like one) in the latest Firefox on windows environment.

Thanks.

It's really easy to add your own Image to toolbar buttons. Read these links you'll have your answer & don't forget to link your images for the buttons in CSS file.

For example:

<window id="main-window">
  <toolbox id="navigator-toolbox">
    <toolbar id="xulschoolhello-toolbar" toolbarname="&xulschoolhello.toolbarName.label;"
      accesskey="&xulschoolhello.toolbar.accesskey;"
      customizable="true" mode="icons" context="toolbar-context-menu" 
      defaultset="xulschoolhello-hello-world-button"
      insertbefore="PersonalToolbar" />
  </toolbox>
</window>

CSS File:

 //LInk you image here//
    toolbarbutton.xulschoolhello-toolbarbutton,
    window:not([active="true"]) toolbarbutton.xulschoolhello-toolbarbutton,
    toolbar[iconsize="small"] toolbarbutton.xulschoolhello-toolbarbutton {
      list-style-image: url("chrome://xulschoolhello-os/skin/toolbar.png");
    }
