685710 - Profile loss after Firefox updates

Status: RESOLVED INCOMPLETE

(Toolkit :: Startup and Profile System, defect)

Description

[[:Cww]]

With every Firefox update, some users seem to end up restarting with a brand new profile.  I don't know what triggers the installer to reject the existing profile and make a new one but it manifests as near-irrecoverable data loss on the part of the user.

Ooops, hit submit before putting in links:

https://support.mozilla.com/en-US/questions/864596 mentions a crash and definitely got a new profile

The following people only talk about bookmarks but from experience, they often have lost other things:

There are lots of other reports where only one file or another in the profile was broken.  That's probably a different bug.

Given that this report is 6 years old, the reporter's account has been disabled, and it was filed on behalf of a bunch of sumo threads (that must also be >= 6 years old), I don't think we can do anything here.
