 Replying to [comment:2 arthuredelstein]:
 > In #15502, to save time, we disabled `URL.createObjectURL(...)` in Web
 Workers. For FF38, we should try to rewrite this patch to  properly
 isolate blob URLs to first party domain in Web Workers rather than
 disabling them.

 I've created #16429 to remind us about this issue still being unresolved.
