some Themes don't work with the current TB 17 in this case you can try "Titlebar Tabs Cleaner"

Diese Bewertung wurde für eine vorherige Version des Add-ons (3.42) abgegeben. 

Thanks for the info Mark.For other users : With Titlebar cleaner, Noia2 theme works with TB 17. Nevertheless, you'll have to adapt inside the xpi file, three install.rdf files to support the TB max version. Put 17.*, it's OK.And of course, you'll have to accept a few visual bugs. I work on an update. Be patient ...
