+++ This bug was initially created as a clone of Bug #1015157 +++ Implement the solution in bug 1015157 on Windows 7 & 8

Note that it's possible that bug 672885 (blocking bug 590945) is not an issue for Windows 8 (which uses newer DirectX) so we may be able to do Window frame stuff (like bug 590945) for Win8+.

If I read bug 1015157 comment 6 correctly, the only thing we need to do here is add a grey border to the left and right side of the tab bar. Philipp, is that right?

Philipp, is > that right? Yes that's the main thing. Note that this is only for Windows 7 and 8 though. I just saw that Zhenshuo didn't include a mockup for Windows XP in the bug (round corners on the theme would be really helpful there), but I can find that.

Hmm, I'm not sure if ::after:not(:-moz-lwtheme) works. Changed to :not(:-moz-lwtheme)::after.

Comment on attachment 8493688 [details] [diff] [review] lwtborder.diff Review of attachment 8493688 [details] [diff] [review]: ----------------------------------------------------------------- With my apologies for the delay here. This looks kind of awkward in the top-left corner because of the top border we use for lwthemes... but I'm not really sure how to fix that, and I think this is a strict improvement, so let's at least take this.
