dmose was seeing this, and we didn't manage to figure it out last week.

IIRC it was a startup crash a few seconds after launch, on release, and not fixed by reuploading bookmarks.

dmose, could you confirm, and add any more things you've tried?

If you're feeling super helpful, you could run current master of the firefox-ios repo in Simulator from Xcode, sign in with your Firefox Account inside the simulator, and get a stack!

The README in the repo should be up-to-date enough that you can build and run without too much trouble.
I can confirm this.  It seems to happen somewhere shortly after startup on probably 98% of invocations.  It typically happens between 1-10 seconds (often 3-5) after startup.

Things I've tried so far:

* rearranging bookmarks in the bookmarks window on the desktop, and waiting a while
* turning off bookmark sync on firefox on desktop, turning it back on, and waiting a while

this is on an iPhone 6+ running 10.1.1 (currently, though I've been offered a 10.2 upgrade which I'll probably accept before too long).

I'll see about generating a build...

And if you kill Firefox (swipe away in the app switcher), go into airplane mode, then launch Firefox, you don't get a crash?
It didn't crash on master.  Lots of complaints in the sync debug log, which I saved.  I can upload it somewhere, if you like (not sure if these logs can contain personal info or not).
Will try the airplane thing momentarily.
Indeed, starting in airplane mode hasn't crashed after a couple of minutes.
Fantastic! That implies it's a bug we fixed already. Could you email me all of the sync logs you grabbed? (They shouldn't be personally identifying, but I can at least filter out the irrelevant bits if we need to live on this bug.)

Sent.

I thought this might be Bug 1317096, but that wouldn't cause a crash, and would have been resolved with unchecking bookmarks.

Other than that, the log doesn't look too concerning.

Bug 1315755 is a possibility.

Let's hope that this continues to work for you in 6.0, Dan; I'm happy to have a successful mystery. I'll ping Stefan to see if we can add you to Test Pilot to try out the 6.x branch on your device.
And by Test Pilot I mean TestFlight. ☕️

Interesting.  My device is not jailbroken, FWIW.
We can also reach out to ckarlof, who mentioned a very similar sounding crash on his iPad.
