userChrome.css Tabs at Bottom covering content

I have moved the tabs to the bottom but now the tabs are covering some useful content. Is there a way to pad the content bottom or some other way to move the content up to make way for the tabs? I've tried everything.

Here's my current code:

@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); 

#main-window:not([inFullscreen]) #content-deck {margin-bottom: 32px !important;}
#main-window[inFullscreen] #content-deck {margin-bottom: 0px !important;}

#TabsToolbar
{
   position: fixed !important;
   bottom: 0px !important;
   width: 100% !important;
}

#tabbrowser-tabs {width: 96% !important;}
#TabsToolbar[inFullscreen]
#TabsToolbar { background-color: #4d4d4d !important }
#tabbrowser-tabs { background-color: #4d4d4d !important }

As you may know, the author of Classic Theme Restorer maintains a large set of CSS files with intricately detailed rules for moving the tab bar. The ones to move the tab bar below the content start here, and incorporate several additional files:

Hi abt, it might be beneficial to follow up with the source of the rules you're using, to make sure they are current with the latest release of Firefox. Do you recall where you got them?

P.S. Use <pre> before and </pre> after your code to preserve its integrity.

#main-window:not([inFullscreen]) #content-deck {margin-bottom: 32px !important;}
#main-window[inFullscreen] #content-deck {margin-bottom: 0px !important;}

#TabsToolbar
{
   position: fixed !important;
   bottom: 0px !important;
   width: 100% !important;
}

#tabbrowser-tabs {width: 96% !important;}
#TabsToolbar[inFullscreen]
#TabsToolbar { background-color: #4d4d4d !important }
#tabbrowser-tabs { background-color: #4d4d4d !important }

@jscher2000 Thanks.

No, I don't recall where I got the code other than I searched, found, and tried lots of different ways and this is what I went with. Many of them worked but they all have the same problem, the tabs cover the content.

Duly noted on using the pre tag. I have edited my post.

Try to add a "display:block !important;" rule:

#TabsToolbar
{
  display: block !important;
  position: fixed !important;
  bottom: 0px !important;
  width: 100% !important;
}

Thanks. No luck with that. I the problem is that this moves the tabs tools bar and what I'm trying to do is resize the content so that the tabs aren't over the top of it.

Can you attach a screenshot?

Okay, so I think I may have been misleading with my post (sorry!). When I said I want the tabs on the bottom I meant the bottom of the screen not the bottom of the navbar.

I've attached screenshot of what I mean by the tabs covering the content.
