Inactive color for URL doesn't work

I want to customize the TAB colors NOT have the entire bookmarks bar change colors too !

This add-on would get 5 stars if only the user could disable the drop shadow on the text within the tabs as an option.
When you need a contrasting text/background, the drop shadow makes black text on white background look VERY blured and very indistinct making tab text rather difficult to see.
If only I/we could disable the drop shadow on the tab text this would be a great add-on.
