Note: You should avoid using arguments.callee() and just give every function (expression) a name.

Warning: The 5th edition of ECMAScript forbids use of arguments.callee() in strict mode.

No rush, we just need to change them as and when we patch those uses.
}

That seems to be a good G.F.B. to me...
It can be done in chunks, in blocking bugs, as need be.

NB: It may be worth fixing Firefox code first, when SeaMonkey copies it.

Don't do that Gerv is about to land a tree wide change to the MPL headers.

Replaced arguments.callee() with a name. (v1)

[Don't need to bother with licence changes, Gerv will sort things out.]

Sorry, but I don't appreciate your choice of function names. Try to make up a meaningful, but not too long, name that would be useful in a stack trace. For instance, "tab2Loaded" could work well here. (Note that this is actually my third attempt at a function name, so feel free to improve on it.)

>+    popup.removeEventListener("popupshown", triggerPopupPopupShown, false);
Nit: PopupPopup looks cumbersome. Just use triggerPopupShown.

>+      aSubject.addEventListener("load", function observeASubjectLoad(aEvent) {
>+        aEvent.currentTarget.removeEventListener("load", observeASubjectLoad, false);
I don't think it makes sense to include "observe" here, just use aSubjectLoad.

>+    duplicateTab.linkedBrowser.addEventListener("load",
>+                                            function testTab2DupLBLoad(aEvent) {
Nit: incorrect wrapping.
I don't think it's possible to wrap this nicely, so don't bother.

Wow, how did those sneak past their original review ;-)
