I have been using Nightly since V8.0. All of a sudden my "Navigation Toolbar Icons" style changed on "Nightly V14.0a1". They used to look exactly as the ones displayed in Firefox V11.0. This occurred before a nightly update.
Compared the about:config's between Firefox and Nightly, reverted to an older Nightly version, Re-Installed nightly and also Started Nightly with ALL addons disabled but could not come up with a solution.
The icons respond to their corresponding actions. It's just the looks.
The attached image shows the icons differences. Any suggestions?
