I locked the background change option but firefox has a hole that still allows for the background to change. Is there a way to disable that option on firefox as well?

Add code to the userChrome.css file below the default @namespace line.

The customization files userChrome.css (interface) and userContent.css (websites) are located in the chrome folder in the user profile folder. 

@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* only needed once */

#context-setDesktopBackground { display:none!important; }
