Iron Man theme

A theme inspired by Foxdie for Firefox. For better appearance it is recommended to set the bookmark bar to be always visible (Ctrl+Shift+B within a tab). Tested for up to 1080p. Works great with Speed Dial 2 plugin for Chrome. I would also like to provide the new tab's background for use with a custom extension: https://i.imgur.com/HxCGGFy.png
