Are there any crash ids in chrome://crashes that have the same timestamp as the crash you experienced?

I'm afraid not. To my knowledge I have not disabled the crash report either.

Another piece of information that I discovered after my report: everything in chrome://apps/ was gone as well (except Web Store). I took my laptop down to TechStop, and since I haven't installed any apps in weeks, they were able to recover them from the online version of my profile, but only after removing the profile folder from the local directory (I think that's what they did. I know that it wasn't syncing automatically and they needed to do some manual TechStop wizardry to get the apps back).

Did you notice any other problems with your machine? Sounds like your part of your disk was wiped.

I haven't noticed other issues with my machine, though to be fair there are very few other parts I use; my images folder appears to have all its files intact, GIMP and Sketch still run, and the notes in my notepad are unaffected, but those are the only local things I really have.

Based on what I heard at TechStop, my running theory is there were two parts to the incident:

--There was the crash itself. I don't know if it crashed because of what I was doing (inspecting page html) or something going on behind the scenes.

--Second, there was the local Chrome profile no longer syncing to my global one and/or no longer tracking my history. This behavior appears to coincide with, and may somehow have been set in motion by, the shifting of my roles and permissions within Google at the beginning of last week, though I couldn't speculate on how.

If this is the case, the second part had been ongoing for awhile, but I'd not noticed it prior to the crash happening. I'm not sure how the loss of the Chrome Apps fits into all this.

WRT comment #5, had you been running the same launch of Chrome since conversion?  I mean like a bunch of stuff may have stopped working earlier, it just hadn't been surfaced until the crash happened?  I'm wondering if something about the transition caused the new activity to not be recorded, and when you restarted the previous state was considered current.  I don't think there's any revision history which would be helpful for something like that.

I would suggest trying to make sure an orderly shutdown results in expected state when you startup, just in case it's still happening!

I'm not sure what you mean by the same launch, but I had not manually updated Chrome since conversion, and to my knowledge I haven't shut it down / had it crash since well before conversion.

I agree that the most likely culprit is something about the conversion caused new activity to not be recorded. Right now, my history does appear to be recording correctly, but I'm terrified of shutting it down again for fear of it not coming back the way it'd be expected to, and there's just an overwhelming number of tabs to try and make note of them all.

FYI, I've found another place where expected data is missing (though I don't know if it's related to the crash): my app passwords logged at go/asp

Thank you for providing more feedback. Adding requester "rohitrao@chromium.org" for another review and adding "Needs-Review" label for tracking.

Have you experience any data loss since this initial incident? Is the data you lost still lost? 

A similar incident has not occurred since the first. The 10 days of browser history, and the state of my session at the time of the crash, were never recovered AFAIK.

Data on go/asp is not linked to chrome. The fact that it is missing as well, hints some account change that could affect chrome sync. This would explain that open tabs data was not synced to server.

Unfortunately I cannot investigate reason for crash without crash_id or dump.

I'm closing this bug as NotRepro. Feel free to reopen if issue happens again and include screenshot of about:sync.

Understood. To wrap up: there remains a 10-day gap in my Chrome browser history between June 6 and June 16 (during which time my activity was not recorded). There appears to be no gaps since then. When I've shut down Chrome, it has restarted with all browser tabs saved.

I am somewhat doubtful that whatever happened will affect me, personally, again since there is a lot of circumstantial evidence indicating that a key factor in the event involved something in the employee conversion process.

I do worry that this unknown bug could affect other conversions unwittingly, and that it will be difficult to diagnose (or even report) since they will be as unprepared to handle it as I was. I can't offer much in the way of help or suggestions to move forward, except to say please keep an eye out for similar reports so that other people don't have this happen to them.

Thanks,
Nathan
