It looks like we can potentially remove this warning:
https://searchfox.org/mozilla-central/source/dom/indexedDB/ActorsParent.cpp#13939

As I read this, we'll generate the error if we need to invalidate active transactions.  We do expect this to happen during the normal course of operation if a window/worker closes while it still has active transactions.  In particular, we've added a number of new control flow paths this year that will explicitly invalidate transactions that previously would have ended up self-terminating when the IPC messages attempted to dispatch results to a dead JS global.

I would expect advertising iframes to be the most likely cause of this happening based on what I'm theorizing above.

I think we just want to remove the above call to IDB_REPORT_INTERNAL_ERR().  If we want to keep it, we need a comment explaining why.

Jan, do you agree?

Yes, we should either remove it completely or convert to a debug only warning.

Tested with Firefox Beta 62.0b15 and managed to reproduce only the error:"IndexedDB UnknownErr: ActorsParent.cpp:13930" covered in bug 1475488.
I cannot reproduce the errors in Firefox Release 61.0.1.

Based on the above I will mark FF 62 and FF 61 unaffected.

Closing as I can't repro this anymore and this is quite old. ActorsParent.cpp has been changed very actively, so I guess this is probably fixed at some point.
