Hello,

I am the sysadmin of a network, and I see the following message on some
computers:

"It looks like you haven't started Firefox in a while. Do you want to
clean it up for a fresh, like-new experience? And by the way, welcome back!"

But the people work every day on this machines and on this profiles. And
when you click the message away, it comes again when you start Firefox.

The clients are Linux, and the homedirs are on NFS.

Can somebody tell me what triggers this message exactly?
Or what could be wrong?

With regards,
Paul van der Vlis.

I couldn't find anything on it except in the bug for implementing the
prompt, <https://bugzilla.mozilla.org/show_bug.cgi?id=498181>.
According to comments there, it depends on Firefox knowing when the
profile's lockfile was last replaced. In particular, people get the
prompt if Firefox finds an old lockfile in the profile. So I think
it's reading/writing/timestamping of lockfiles you should look at if you
want to get at the cause.

There's a thread at
<http://forums.mozillazine.org/viewtopic.php?f=38&t=2766881> in which
someone "solved" the problem by touching every lockfile.

But since Fx 29, you should be able to disable the prompt entirely by
creating the pref browser.disableResetPrompt and setting it to "true",
which is probably easier than investigating lockfiles.

This is interesting, thanks. I see that many browsers do not update the
".parentlockfile", but I don't understand why. They are started every day.

That's what I did, but I am interested in the "why", and in the "what
triggers it".

With regards,

When I change the .parentlock file, I can reproduce the problem.
--------
cd ~/.mozilla/firefox/0k48lsbe.default
touch -t 201405101024 .parentlock
-------

Now the new question is: Why is .parentlock sometimes not updated when
the browser starts?

Were there any previous crashes or stuckages with Firefox earlier?

Yes. It are NFS homedirs and I've seen some problems.

I've seen that Firefox did not want to start, saying it's already
running. And I saw twice a locked profile (no answer on an "ls" there,
but no problems in the rest of the homedir).

Most of the time it works OK, but because of these problems I am looking
at this.
