Theme development info
======================
This theme is originally based on the default FF4 theme.  The first version of the default FF4 theme that it was based on was the one bundled with
Firefox 4.0b12, and so that's kept under this directory (in 'ff4 default themes') for reference.  We've changed various files radically (such as
browser.css) to make them look nicer, so as new versions of Firefox get released and the theme may get updated, we'll want to store the later versions of
the default distributed theme in sibling directories (if the default theme changes at all), so we can do a diff between them and decide whether we need to
update anything in our theme based on what's been changed in the default theme.  All the while, though, we should always be able to apply our theme to the
default theme by just copy/pasting (overwriting) the files we modified/added (specified) into the default theme.  This should turn the default theme into
our theme.

We only override 3 packages of the default theme, as we specify in this theme's chrome.manifest.  They are:
- browser...classic
- toolkit...global
- toolkit...mozapps

We don't bother with a separate 'aero' theme; it should just use the same theme files as other platforms.

Access some key files through these URLs from within the browser:
- chrome://browser/skin/browser.css
- chrome://global/skin/toolbarbutton.css

Note:
There are 2 'bookmarks' buttons in FF4; one which displays the bookmarks sidebar, and one which is a dropdown.  The dropdown (which you'll find in the DOM
Inspector with the ID 'bookmarks-menu-button', for some reason, *GETS HIDDEN* when you are displaying the Menu Bar.  So, to see it, you need the Menu Bar
disabled and so you'll have (in Windows) the orange 'Firefox' button in the top-left.

Theme files modified (should be able to replace these from the equivalent 'ff4 default new' theme folders and it'll apply my theme changes to the default):
