484777 - Session restore is not restoring most recent session after crash

Status: RESOLVED DUPLICATE of bug 366509

(Firefox :: Session Restore, defect)

Description

[Tim Powell]

Using 3.0.x (just happened with 3.0.7) I've experienced this multiple times: I browse for a while with multiple windows and tabs open, often for days or weeks at a time, then Firefox crashes. When it restores the session, it is from quite a while before. If I check the history, I see that the very latest visited sites are in the history, but the tabs and windows are not restored. I know for a fact that those tabs and windows were not closed but were not restored. I also know that some that were closed previously were (incorrectly) restored.

I have been unable to pin down specifics of what is getting restored. I don't think it is from the last clean quit. Most of the crashes leading to broken session restores have been random, perhaps memory-related -- they may occur after restoring the laptop from sleep and flipping through tabs.

I know this is terribly vague, but I did not see a bug about restoring what appears to be a PREVIOUS session. (I saw a number that point to specific cases where nothing is restored)

Other things that may or may not be relevant: I have Firefox set to show my windows and tabs from last time on startup. I frequently have to switch between using and not using a proxy (work vs. home). It is most likely that the only reason Firefox was previously shut down is due to a discovered upgrade (eg 3.0.5 to 3.0.6 to 3.0.7, etc.) In cases that I recall, the upgrade is properly restoring the session. I am a heavy browser user: I almost always have 15 to 30 windows open with 5 to 20 tabs in each.

This is happening to me on Vista 64. In my case I can tell whether a restore will work after the next crash because sessionstore.js is not being written while I'm browsing.

I originally reported it as bug 470355, but Firefox had stopped crashing for me at the time. Now it's crashing again.

Probably the same issue as bug 480876. This could be either extension related or even be a variation of bug 406378 (i.e. your file system failing to write the current session to disk before the crash and then finding an intact older version instead).

Both of those bugs include the computer crashing.

I should have said that it either works or does not work for the entire session. It doesn't seem to write sessionstore.js for a while and then stop in the middle of a session. I usually look at the timestamp when I start Firefox.

And I'm getting these errors:

Error: [Exception... "Component is not available"  nsresult: "0x80040111 (NS_ERROR_NOT_AVAILABLE)"  location: "JS frame :: file:///C:/Program%20Files%20(x86)/Mozilla%20Firefox/components/nsSessionStore.js :: sss_saveState :: line 1909"  data: no]

Right, that's a Firebug related issue, then, which has been fixed for the upcoming Firefox 3.5.
