Discussed during triage. During the last 6 days this is averaging about 200 crashes per day, I was asked to reach out to Adobe regarding this bug to see if anything can be done regarding this. All versions of Windows are affected.

I've opened FLASH-4191239 for this. I don't see a smoking gun based on my quick triage. I'm happy to provide more color offline.

Marking P3 based on volume.

Bulk change of P3 carryover bugs to wontfix for 68.

This is the generic signature for sandbox-related crashes. This is not anything actionable on its own. If plugin-container crashes in this call, it means that the IPC channel between the proxy layers in plugin-container and the sandbox process have unexpectedly been closed. The crash reporter typically only captures the stack from plugin-container in that case, which isn't helpful -- the stack from the sandbox process is what we need.

Absent a stack trace from the crashing sandbox process, a repro case that causes this report would let us attach a debugger to the sandbox process to try and catch the crash.

ESR 78 is the last Firefox version to support Flash. We still see a couple of these crashes per day from ESR 78 users. We can close this bug after we EOL ESR 78 on 2021-11-02.
