Tried both in Sample Browser and Fenix, and can't reproduce this so far. From crashstats it looks like a web render problem, but even after enabling web render, I am not seeing the crash.

Hi, I'm trying to reproduce this (for https://bugzilla.mozilla.org/show_bug.cgi?id=1645841) but I can't see Decentraleyes in the list of available addons to install in Fenix nightly. Is there something I need to do for it to appear, or a way to sideload it?

[csadilek]

@jamienicol this hasn't landed it Fenix Nightly yet, unfortunately. This happened in a custom build for QA. If you want to try with a local build I am happy to send along instructions. Otherwise, we should have this in Nightly soon.

@csadilek Instructions would be great if it's not too much trouble!

Hi Christian,
I was able to reproduce the crash again today on 6/16 Nightly debug build #21680829, GV 79.0a1-20200614092422, AS: 60.0.0

Thanks, @softvision-miralobontiu. We'll investigate :).

I have been unable to reproduce this on my Pixel 2 (Android 9 and 10), OnePlus 6 (Android 10), or Moto G7 Play (Android 9).

@softvision-miralobontiu, if I provide you with a gecko patch with some logging added, would you be able to build Fenix with the patched gecko and attach the logcat from the crash?

@jamienicol, I was able to reproduce the crash again, today, with Samsung Galaxy Tab S6 (Android 9), on a Nightly debug build from 6/22, with GV 79.0a1-20200617093637, AC: 47.0.20200618130101, AS: 61.0.2:
