This is not migration related and happens in Fenix Nightly too. Still not often though. Maybe there is a very specific configuration that ends up with no search engines?

This is probably a dupe, but this is now a high frequency startup crash on 79b4 and 79b4 - so I am marking it as a blocker.

This looks like it was fixed by mozilla-mobile/fenix#11875 as long as we have that on the branch we should be good.

@kbrosnan Seems issue is still present in org.mozilla.firefox_beta-79.0.0-beta.4 should I open another issue for it?

[pocmo]

This is a somewhat older build too. 81 is currently on the beta track.
