If you are in search for a new dark theme to replace your Christmas themed one you got last week, have no fear – I have a good one for you.  Glaze Black is a simple and flat theme for Firefox.  Oh, did I mention it is black too?  You can oooooh and awww at the screenshot below:

As you can see, it has a very simple look and feel to it (which is something I like to look for in a theme, personally).  You can pick it up on the Firefox Add-ons web site and be sure to stop by and see the creator of the theme at theme-oasis.org.

As a ‘bit of an extra tip – you can pick up a white version of this same theme here.
