Chosen solution

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 */

#addon-bar[moz-collapsed="true"] { visibility:visible!important; }

If you still wan to be able to hide the Addon bar then use:

#addon-bar[moz-collapsed="true"][collapsed="false"] { visibility:visible!important; }
