Preferences Menu Rated 4 out of 5 stars

This theme is my favourite! I only have one problem, I can't find the preferences menu - I tried your earlier suggestion to go to the "About" section by right-clicking the theme, but there is nothing to change. The link to your homepage doesn't give any more information either, so what shall I do?
Oh, and is there a possibility for me to get rid of that grey 1px line between the menubar and the toolbar?
Thank you!

Not supported in 3.6

I assume you're using 3.6 and I'm afraid Mozilla forbid to use such code in a theme since this version.
Read the Release Notes and you will understand how to do that.
This theme is discontinued so no new changes will be made.
