1234749 - "Restore Session" information is incorrect and does not contain information about the most recent pre-crash environment, under some circumvstances.

Status: RESOLVED INCOMPLETE

(Firefox :: Session Restore, defect)

Description

[Peter Capek]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:42.0) Gecko/20100101 Firefox/42.0
Build ID: 20151029151421

Steps to reproduce:

In 42.0, and at least some earlier versions, if there is one or more open "Restore Session" tab(s) present at the time of a crash, then the "R-S" information may be wrong and include only some, or perhaps none, of the open tabs at the time of the most recent crash.    I believe that it may be picking up obsolete (from an earlier session) checkpoint information in some situations, since all the recovery information is familiar but obsolete, but I don't know the details of the mechanisms used.

I have been having a lot of trouble with FFx 42 (& prevs) crashing... sometimes 3 or 4 times A DAY.   No obvious pattern or commonality; generally not doing anything not widely done (gmail, finance.google.com, slashdot, YouTube &c.    On MacOS 10.8.5.


Actual results:

When FFx crashes while I'm interacting with it, the R-S page after restart sometimes DOES NOT INCLUDE the page I was viewing, and also does not include other pages which I know were present at the time.   (These are not pages which were opened in the few seconds preceding the crash, so it's not a matter of them not having seem checkpointed yet!)


Expected results:

Restore session information should be time-stamped, and time-stamp should be visible in the "restore session" page after restart.   I have had so many crashes that I sometimes have 5 or 6 open "R-S" tabs I'm trying to recover and restore tabs from.

I am continuing to experience this problem.   I just suffered a crash and the "Restore Session" page listed sites that I haven't visited in at least a week, and had none of the (few) sites that were open just prior to the crash.   Is there any hope of getting someone to look at it?   The prospect of losing info about open sites (as just happened) is making me contemplate moving to Safari or elsewhere.

Peter, does this still happen for you when using a more current version?
