Ok that should be pretty easy.
1. Download Stylish addons.mozilla.org/cs/firefox/…
2. Go to url about:addons
3. Click on user styles
4. Click on Write new style
5. Type there some name of style it doesn't matter what
6. And copy to the textfield this:
    #nav-bar {background: linear-gradient(rgba(253, 253, 253, 0.45), rgba(255, 255, 255, 0)) !important;}

Thank you for the information with Stylish.
I used this codes:
#nav-bar {background: linear-gradient(rgba(255, 255, 255, 100), rgba(255, 255, 255, 100)) !important;}
#personal-bookmarks {background: linear-gradient(rgba(255, 255, 255, 100), rgba(255, 255, 255, 100)) !important;}
to get the background white.
But I have two problems.
Example of my problem there you can see that the background of the active tab and the startpage/home (Startseite) are not white.
If you can tell me the code for these two elements it would be very nice.Sweating a little...

Ok with the tab there is little problem I personally try to figure it because of my Firefox Ribbon UI for Firefox 29+ but I still didn't find all things too do what I need. But for you I have advice. the tab is made out of 3 parts which are called: .tab-background-start, .tab-background-middle, .tab-background-end so I hope this might be helpful if not then tell me :D

About the Startseite I don't know in my browser it is not blue but you can try those 2 plugins to get the name of class or id of this element:
addons.mozilla.org/cs/firefox/…
addons.mozilla.org/cs/firefox/…
then you will just click the are with right button and click inspect it is really easy to use :D

Hope it help if not just leave me message :D

Sorry but the tab codes didn’t work for me, but the plugins work perfect.
With it I inspect the Startseite, but first it didn’t work.  I have to inspect the Startseite background in the customize tab and then I found out the id of it. (screenshot of it)

The active tab has at the moment a white background with the plugin Classic Theme Restorer. With it you can change the background color of the active tab. This plugin I have installed because I use a Windows 8 theme for windows 7 and firefox had a problem with this theme. (see screen) So I have to use Classic Theme Restorer with the settings: "Remove tab toolbars background fog (Windows AeroGlass)" to fix the green background on top.

Now all works perfect.  Clap 

I have my good old Windows 7 with a Windows 8/8.1 theme and a Firefox with a Windows 8/8.1 design. (see screen) :D (Big Grin) 

I’m using these Stylish codes:

      #nav-bar {background: linear-gradient(rgba(255, 255, 255, 100), rgba(255, 255, 255, 100)) !important;}

      #personal-bookmarks {background: linear-gradient(rgba(255, 255, 255, 100), rgba(255, 255, 255, 100)) !important;}

      #PersonalToolbar {background: linear-gradient(rgba(255, 255, 255, 100), rgba(255, 255, 255, 100)) !important;}

And the plugin Classic Theme Restorer to get the active tab white.

Thank you for your help :happybounce:
