[SessionStore] Get rid of the unnused "Undo Close Window" code


(Firefox :: Session Restore, defect)

Not set



Firefox 2 beta2

The code is mostly there, it's just not exposed to extensions and thus of no value at all (except for filling RAM). The Undo Close Window API should pretty much mirror the Undo Close Tab API. Additionally browser.sessionstore.max_windows_undo should default to 0 since in most cases this functionality won't be used at all.

An alternative approach would be to completely drop all Undo Close Window code and let extensions implement it on their own should they want to. An extension would then have to get a window's state onunload and restore it as a partial session (see bug 344640 for the required API).
It's probably better to leave this to extensions than to ship hardly tested code which won't be of any use except with an extension.

Drivers: There must be a patch of some kind to this bug since we're currently storing all data for the 10 last closed windows (since startup) for no reason at all.

Checked in on trunk. We should evaluate this again for a later release. However seems a low priority given the trend of favoring tabs instead of windows.

remove all Undo Close Window code

Very low risk, removing unused code.

I filed bug 360408 to investigate putting the "Undo Close Window" code back in (but with a "Recently Closed Windows" menu this time).
