Note that you can edit the text and accentcolor of a lightweight theme (Persona) via the lightweightThemes.usedThemes pref about:config page. The first entry is the currently selected theme.

What code in userChrome.css did you try?

You may have to add -moz-appearance: none !important; if you can't override specific rules.

Try this selector:

#TabsToolbar toolbarbutton, #tabbrowser-tabs  { background-color: #xxxxxxx !important; }

Hi, thanks for the response.

What you posted was actually able to help change the color of the tab toolbar, but the results weren't quite what I was expecting. It seems there's more to getting this the way I'd like than just changing a single color for a single element.

I've included another picture that shows (at the top) what your code gave me, and (at the bottom) what I was hoping the result would be.

This add-on may do what you want,

Classic Theme Restorer (Customize Australis) {web link} Restore squared tabs, appmenu, add-ons bar, small button view and more on Australis UI (Windows/MacOSX/Linux + Fx 29+).

This will restore many of the things the last upgrades took away.

Thank you, I've already got Classic Theme Restorer installed. It's how I've been able to make it look the way it currently is.

I've been looking at just creating a "Persona" that is nothing but a solid color. Is this something that gets "reviewed" by an actual person, or is everything just automated and I get a link to my newly created theme right after I submit?

I've basically given up on this. You'd think it would be simple, but it's proving to be a huge pain that's taking far too much time for what I want.
