Can you please link to your crash report from crash-stats? This doesn't crash for me on Desktop with Fission enabled (on OSX). Thanks.

How can I find Fenix 78 on crash-stats? I can only see 76 there.

Is there some kind of about:crashes page you can look at to find your crash report? I don't know how crash reporting works for Firefox Preview.

There is about:crashes but it says no crash reports have been submitted. 🤔 It might be using Play Store way of crash report, not sure.

Got the crash report, as somehow about:crashes does show something today:

Thanks for the crash report. It looks like this crash is happening inside the Java layer, so a Fenix person should look at it.

The URL in the crash report is an about:neterror page, so maybe something is going wrong with navigating from a web page to an about: page.

We do not currently support Fission on Android.

Could there be a warning for that? Firefox on desktop shows warning when enabling Fission without WebRender, I hope there be a similar one on Android.

On release and beta desktop Firefox, we've locked the Fission pref so that people can't flip it on and cause themselves a lot of issues. Maybe that could be done for Android, too. https://searchfox.org/mozilla-central/rev/4166c15e2a99a23a9b38ad62c9fdfe8e5448b354/modules/libpref/init/all.js#2705-2709

A warning for Fission on desktop without WebRender seems reasonable, because it mostly works, but it seems like it really doesn't work well on Android.

Moving Android Fission bugs to the new GeckoView::Sandboxing component.
