Changing padding between text links in top menu

Hi Tomas,
I am using Tiny Framework (thanks, it’s great!), but I want to make the page links in the top menu more narrow; in Firefox, the menu is too wide, and breaks onto a second line. In Chrome and IE, however, the top menu fits on one line and looks fine.

I have looked in the css files, but I cannot find the place where you specify the padding between the text links in the top menu. I believe that if I could reduce the px/rem space between each page name, I could probably adjust the width to where it looks the same in Firefox as it does in Chrome and IE.

Thanks in advance for any assistance you can provide.

Cheers,
Bud
