We can recreate data from the sessionstore API if needed, and bug 600991 should mean that for most users the ordering data is entirely irrelevant, so we can just sync all tabs, in the order of the window. We should just special-case tabs to keep a score, but not changedIDs, and grab the current tab set when it's time to sync, and make sure it never saves JSON to disk.

I'm not sure what that has to do with disk I/O. > We should just special-case > tabs to keep a score, but not changedIDs, and grab the current tab set when > it's time to sync, and make sure it never saves JSON to disk. Indeed. Patch coming up!

Comment on attachment 489409 [details] [diff] [review] v1 This works, though I'm waffling on .modified as a "public" value. Either way works, it's not like it's really public/not public.
