A dark indigo CSS theme for Firefox and a large collection of privileged scripts to add new buttons, menus, behaviors and other opinionated features. The theme is similar to other userChrome stylesheets, but it's intended for use with an autoconfig loader like fx-autoconfig, since it uses JavaScript to implement its more functional features.

Not aware there was a "Mac version" of MrOtherGuy's 'tabs_on_bottom.css' userstyle... or are you using another userstyle from another author?
