Created attachment 585007 [details] see the deselected message in the middle still has a blue border If you select a batch of messages, click one, move down 5 or 6 and shift-click another one, and then you go to de-select one of the messages in the middle, the background color changes to de-selected but the selection border remains. This makes it hard to tell that you've actually deselected that message.
tested with latest nightly build on win7 with three vertical panels view.

This *definitely* shouldn't be removed. It's the focus-ring for the message, without which you'd have no idea what row is currently focused in the tree. Granted, we need to fix the colors a bit so that you can tell which row is focused when it's *selected* too, but that's bug 686959. Perhaps more importantly, the behavior described in comment 0 is exactly what happens in Windows Explorer, which is the basis of the theming used for the message list.
You are correct, I'm updating the summary. The style does not match explorer. The borders are heavier, doubled up, and darker. The gradient is wrong too.
Summary: de-selecting a message doesn't adjust style completely → selection style doesn't match explorer selection style making deselected items less obvious
Created attachment 585055 [details] selection doesn't match system here's a comparison. we need to match the system. not matching the system is why this felt so odd to me in thunderbird.

The doubled borders are going to be tough to fix, since we're limited by the XUL tree implementation. A while back, I spent an afternoon or two trying to figure out a way to avoid the doubled borders, but it didn't work. Probably the only (sane) way to solve this would be to implement the CSS border-collapse rule on XUL trees, which is beyond my ken. For the color values, there's attachment 562970 [details], which shows all the possible selection states used in Explorer.
