Probably not reproducible, but I currently have a browser where clicking the new tab button opens the tab in the wrong window. The window was probably originally created by dragging the tab to make a new window.

Jeff, can you please try to reproduce this issue on a clean profile or in safe mode?

Nope. I can't reliably reproduce this at all. I expect this is the kind of bug that very rarely shows up and so needs to be solved by inspection or re-architecture. e.g. how does the new tab button decide which window the new tab should go in? Under what circumstances could it be wrong?
The new tab button calls openUILinkIn("about:blank", "tab") which determines the target window via getTopWin():

54 function getTopWin(skipPopups) {
55   // If this is called in a browser window, use that window regardless of
56   // whether it's the frontmost window, since commands can be executed in
57   // background windows (bug 626148).
58   if (top.document.documentElement.getAttribute("windowtype") == "navigator:browser" &&
59       (!skipPopups || top.toolbar.visible))
60     return top;
62   if (skipPopups) {
63     return Components.classes[";1"]
64                      .getService(Components.interfaces.nsIBrowserGlue)
65                      .getMostRecentBrowserWindow();
66   }
67   return Services.wm.getMostRecentWindow("navigator:browser");
68 }

If the window returned by getTopWin() is considered a popup (!window.toolbar.visible), getTopWin(true) will be called.
I think I saw this while testing nightly on 10.8 today and will see if I can reproduce. In my case I was clicking a Socorro link to report and bug and wondering why it was not opening, and instead finally found the link open in another window.

I found this very easy to reproduce on Firefox 11 with a new profile and no addons, on two separate machines (one windows, one linux):

From <script> or in web console, with a single window open:"about:blank","blah","toolbar=yes")

The toolbar=yes causes the window to have a tab bar (which I think is fine; it has always behaved that way).  That tab bar has a new tab button, and that new tab button will open a tab in the other window - as will control-t.

It would be great if this could be fixed, as the ticketing webapp I use at work opens windows in this way, and I prefer new tabs to open contextually - where I have told them to!
I can confirm this issue. 

For my Firefox profile this behaviour occurs for all calls. This is because to avoid bug #294940 I have configured 

  dom.disable_window_open_feature.toolbar == true

so Firefox always uses "toolbar=yes" in calls.

OK, update - this problem appears to have gone away in Firefox 12.  The steps in Comment #5 now gives the desired behaviour (opening in the popup window).
FF12 works for me, too. :-)
