It seems somewhat brittle that we close the two frontmost overlays without
knowing what they are (and implicitly assuming that the second one is the create
profile overlay).

If what we want to achieve here is simply that we go back to the topmost page,
we could add a method OptionsPage.closeAllOverlays(). WDYT?

Yes, I think that is the functionality we actually want here, and I was looking
for such a method. I guess I will have to write it :)

[Bernhard Bauer, 2014/03/10 10:37:36]

Yesplz :)

It shouldn't be too difficult; just closeOverlay() while there is an overlay
page visible.

Done.
