659567 - Huge SS_data for about:addons filled with about:blank children

Status: RESOLVED DUPLICATE of bug 705597

(Firefox :: Session Restore, defect)

Description

[Ed Lee :Mardak]

Attachment: __SS_data for about:addons tab

I have a pinned tab for about:addons, and it seems like I've gone forwards/backwards multiple times, so there's multiple entries.

But the very odd/interesting aspect is that there's a ton of "children" ~350 that point to about:blank each with a docshellID of 0 and various values for ID and docIdentifier.

I've attached the SS_data for the one pinned about:addons tab. It's 1.3MB (the total size of my sesionstore is ~1.4MB).

Most likely not too big of an issue as people probably close about:addons regularly. But odd that there's so many children. ?

If you go to the add-ons manager tab, open the webconsole and run the following, what values do you get back?

window.QueryInterface(Ci.nsIInterfaceRequestor).getInterface(Ci.nsIWebNavigation).sessionHistory.count;

window.QueryInterface(Ci.nsIInterfaceRequestor).getInterface(Ci.nsIWebNavigation).sessionHistory.getEntryAtIndex(0, false).QueryInterface(Ci.nsISHContainer).childCount;

Those child history entries should be session history for the discovery pane but I don't understand why they'd all be blank like that.

I got rid of that app tab (and Firefox no longer beach balls at startup!), but I can re-pin it and see if it happens again.

Oh nevermind ;) I just copy/pasted the __SS_data entry here back into my sessionstore.js and I have it back.

I believe this is from clicking the various side-tabs to switch to extensions, appearance, etc.

I'll leave it open if you want any more data.

out = []; sh = window.QueryInterface(Ci.nsIInterfaceRequestor).getInterface(Ci.nsIWebNavigation).sessionHistory; for (i = 0; i < sh.count; i++) out.push(sh.getEntryAtIndex(i, false).QueryInterface(Ci.nsISHContainer).childCount); out

Also shouldn't this bug take some priority with Snappy project ?

I think this is a duplicate of bug 705597 and has been fixed for Fx 11. Can anyone confirm this?

Ed, do you agree it is gone?
