The toolbar of the standalone message window isn't showing the personas background. On the mac it just has a grey background. The titlebar does show personas, so this looks a little strange.
Created attachment 594267 [details] [diff] [review] Patch This patch sets the toolbar's -moz-appearance to toolbar in standalone window only when no persona is enabled. I also removed the gradient with personas enabled which is shown when the appearance isn't toolbar. And I moved the definitions to messageWindow.css where standalone window definitions make more sense (IMHO).
Comment on attachment 594267 [details] [diff] [review] Patch Yep, I like it, and it makes sense to me. :) r=me, ui-r=me. Thanks, Blake.
