Rated 4 out of 5 stars

Thanks David, this seems like the closest assimilation of the Noia theme of the ones I've tried so far.

Just a couple of changes would make it perfect for me.

One would be to add the text back to the bookmarks on the bookmarks toolbar (would be great as an option)

Second would be to not have the tabs as complete ovals but just oval the top of the tabs and have them come straight down to the page.

Otherwise... best so far, thanks!

This review is for a previous version of the add-on (1.1.0). 

If you don't want rounded tabs : install stylish addon and apply this style :

@namespace url(http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul);
/* ==UserStyle==
// @name Tab: Tabs stylish not rounded.
// @author David Vincent
// @compatible Firefox 4.0+
// @description This changue the style of the tabs.
// ==/UserStyle==*/

-moz-border-radius: 0px !important;
