(note, this is not the same as bug 763269) On Windows 7, with the latest nightly build (and possibly releases) if you exit Firefox from a maximized window and then re-launch, there is a split second where tabs are below the Firefox button in their own tab strip before they shift up to the titlebar where they're supposed to be. This is really quite ugly and makes Firefox feel very slow. I'm asserting this is a snappy:p1 because users see it every time they start and start-up time is our number one performance complaint.
This is a recent regression.

We shouldn't ship this regression. QA, can you help us find the regression window?

(In reply to Alice0775 White from comment #3) Thank you, Alice0775! Matt, can you look into this? This is a severe enough regression that we need a fix or a back out before we uplift to Aurora.

I can reproduce this with the nightly, but not with the latest mozilla-inbound build. I think this is probably fixed by bug 782980 which landed today.
