456980 - [FIX]implement swapDocShells() for chrome content browser/iframe

Status: RESOLVED FIXED

(Core :: DOM: Navigation, enhancement)

Description

[Daniel Glazman (:glazou) (not active in Mozilla any more)]

Bug 113934 implemented a great feature for Firefox users : the ability to move
a tab from one FF window to another w/o dropping context or having to reload the
page.

The same feature for chrome content inside a browser or iframe element would
be very helpful to xulrunner-based applications or extensions for instance
if they implement sidebars. In that case, sidebar items would become movable
between sidebars w/o context loss, and even between a sidebar and a floating
panel for a standalone sidebar item...

Attachment: I think this should do the trick and still be safe

This won't preserve the scroll position, but will preserve the other state here.
