content crash reports with this signature are regressing (again) in firefox 69 from windows machines. they come with MOZ_RELEASE_ASSERT(mWorkerThread == GetCurrentVirtualThread()) (not on worker thread!) and users who opted to submit the crashing url appear to have been browsing some local directory structures through the file:///-protocol mostly.
