Not sure what to make of this error here.

Kris, any idea why this happens? Or do you know who to ask? Thanks!

Comment 3

[Kris Maglione [:kmag]]

It looks like there's a race where we clear a ContentParent's scriptable helper before we mark it as dead and remove it from the pool. My best guess is that it's happening when we hit this branch: https://searchfox.org/mozilla-central/rev/7531325c8660cfa61bf71725f83501028178cbb9/dom/ipc/ContentParent.cpp#1428-1456

If you can try to confirm that, I can probably fix it.

I wasn't able to reproduce it locally, so I can't confirm if that's what's happening or not. 🙁

Tentatively moving all bugs whose summaries mention "Fission" (or other Fission-related keywords) but are not assigned to a Fission Milestone to the "?" triage milestone.

This will generate a lot of bugmail, so you can filter your bugmail for the following UUID and delete them en masse:

Does this disable a wrong test case? This disables the browser_sharedWorker.js in the folder 'browser/component/originattributes/test/browser/', but I think 'netwerk/cookie/test/browser/browser_sharedWorker.js' should be the one that you need to disable.
