Etched for Firefox 3 (Windows version).
This theme matches my windowblinds6 Etched theme for Vista and XP [link]
It is based on the excellent Grapple Yummy Graphite [link] by Aronnax whom I would like to thank for advice.
Shout out to iiswiis for testing!


I have tested the theme with the following extensions:
1. Custom Download Manager
2. Fission
3. Forecastfox
4. Hide menubar
5. Stop-or-reload
I cannot guarantee that it will work well with with other extensions nor will I provide support for them.
Enjoy!

In the screenshot you see wallpaper by Delta909[link] and Pry icons by Jonas Rask

!!! UPDATE !!!
1. New icons: Pry by Jonas Rask (thanks man!)
2. Fixed toolbar separator issue (no need to use userchrome tweak)
3. Several other visual improvements (e.g. unified buttons, no shading over navbar, etc.)

I highly recommend the font tweak that changes your FF fonts instantly. Paste this code into your userChrome, below the @namespace string:*

/* Font Tweaks*/
menubar, menubutton, menulist, menu, menuitem, textbox, toolbar, .tab-text, tree, tooltip
{ font-size: 9pt !important; font-family: Calibri !important;
}


You will have Calibri size 9. Easy to change to anything you like!

*(userChrome is in C:\Users\*user name*\AppData\Roaming\Mozilla\Firefox\Profiles\xh11brgs.default\chrome)
