When I attempt to leave Ion, on the "sorry to see you go" popup window when I click on the "Accept and Leave" button it crashes my Firefox. When I restart Firefox, Ion is still there.
This is not intermittent, it happens everytime.
I am on MacOS Catalina 10.15.7 using Firefox Nightly 87.0a1.
Let me know if you'd like to see the details of the crash report.

Yes the details (link from about:crashes is fine) would be great! IIRC we saw a report like this, on Nightly only, and the crash was somewhere deep in the layout code. It would be good to track down though, I suspect it is related to the <dialog> tag which was fairly new when we built about:ion.
If you want to leave Ion then clearing the toolkit.telemetry.pioneerId pref should do it, but I'd like to follow up on the crash anyway. Thanks!

Thanks! Hm, yes this looks like a crash we've seen before (on nightly only), I'll try to dig up the bug.
Sean, you worked on this in https://bugzilla.mozilla.org/show_bug.cgi?id=1657163 - do you have any idea if the crash here could be related to our use of <dialog>?
about:ion is going to be retired at some point this year so I'm not too worried about fixing it there, but as we start using <dialog> in other places (and web content) I figured it's good to surface this issue now :)

This looks like some display list building stuff, and I recall we've found a bug related to <dialog> and displaylist running in Chrome code.
Emilio, does this look familiar to you?

Bug 1664395 is the one I was thinking of.

Shouldn't be related to bug 1688004, which I guess is what you meant.
I haven't been able to reproduce after a couple times, in neither Linux nor Mac. Can you reproduce this consistently Beatriz? If so, does it happen on a clean profile?

I couldn't reproduce this on Windows 10 or Mac.
