Hey all,
I just wanted to show you how to make a titelbarless Firefox 4 (aka Minefield).

You need:
Minefield http://nightly.mozilla.org/
Stylish https://addons.mozilla.org/de/firefox/addon/stylish/
Hide Caption Titlebar Plus https://addons.mozilla.org/de/firefo...ebar-plus-sma/
Compiz + CompizConfig setting-manager

1. Download and install Hctp and Stylish. Restart

2. Press ctrl+shift+a and open the Hide Caption Titlebar Plus Preferences

make it like in the screenshots

3. right click on the tab bar and select customize.
Now drag and drop the [hcp] Min, Max, Close Buttons next to the app menu (or anywhere you want)

4. Go to http://userstyles.org/styles/44677 and install the style with stylish.

5. Open CompizConfig setting-manager (ccsm) and navigate to Decorations.
In "decoration for windows" add : & !(class=Minefield & state=maxvert)

This will remove the title bar when minefield is maximized

Now your Firefox 4 should look like this when maximized and should almost take the same space as Chrome/Chromium

I also made a Hctp theme for orta http://userstyles.org/styles/44686
