This is a follow-up to bug 1004850, which would make it more useful when the user's session is restored. Right now we just stored closed tabs in memory, but we could also write them to disk if we want to restore them.

I think this should do the right thing, but I'm having a hard time testing it. I tried flipping the session restore pref to always restore my session, then killing and re-launching fennec, but I'm finding that state.windows[0].closedTabs is always undefined. How does writing to sessionstore.js and sessionstore.bak work? I see that we're writing to sessionstore.js in _saveState, but reading from sessionstore.bak in restoreLastSession.

Comment on attachment 8504981 [details] [diff] [review] WIP - Save closedTabs when saving session to disk Review of attachment 8504981 [details] [diff] [review]: ----------------------------------------------------------------- This looks OK to me at first glance. I guess it'd be worth throwing in some logs where you're setting normalWin.closedTabs to make sure it's getting saved in the first place (and has the expected values).

Vivek, maybe you would also be interested in taking this bug after wrapping up bug 732752.

Margaret, thanks I will take this bug.

This is in continuation to Margaret's WIP. As discussed over irc, handled closedTabs in SessionParser and cleaned up restoreLastSession method to process data only from Java.

A new patch with review comments addressed. This patch folds Margaret's and my changes to a single patch. A try run for changes as separate patch can be found at: https://treeherder.mozilla.org/#/jobs?repo=try&revision=e4aa36cf716d
