Hi Jeromie, we're seeing this signature spike pretty heavily recently. Is this something you'd be able to look into?

Comment 2

[Jeromie Clark]

Absolutely, thanks for the report.  I've opened FLASH-4190453 for this.

Marcia, we see a precipitous drop in reports after October, but I can't tie this to a specific changelist. It appears to be fixed (or at least back to baseline). There's no obvious smoking gun in the stack to drive useful further investigation.

Yes, I can definitely see the dropoff in the graph. For 63 and 64 it looks like we were under 200 crashes. We can see if that stays the course on 65.

I don't know why I updated the status flags, but I guess the update is correct so I'm not going to undo it.

Comment 7

[Marcia Knous [:marcia]]

68/69/70 are affected. Current correlations: (95.32% in signature vs 00.43% overall) Module "NPSWF32_32_0_0_223.dll" = true
(95.32% in signature vs 00.43% overall) flash_version = 32.0.0.223

2142 current crashes during the 68 release cycle.

Comment 8

[Jeromie Clark]

We've looked at this in depth, and I'm happy to provide more technical background by email, but it doesn't look like we're going to make headway on this without an interactive debugging session. This is related to the 32-bit sandbox on Windows. Affected users could move to 64-bit Firefox, where this would never be an issue. We really need a repro case to make further headway here, or we could disable our sandbox should a native 32-bit NPAPI sandbox in Firefox become available.

[Chris Peterson [:cpeterson]]

ESR 78 is the last Firefox version to support Flash. We still see about 50 of these crashes per day from ESR 78 users. We can close this bug after we EOL ESR 78 on 2021-11-02.
