Bill, I see you are the owner of bug 1384336. Can we improve these regressions or should we accept them?
Component: Untriaged → DOM: Content Processes
Product: Firefox → Core
I'd like to investigate this, but I probably won't get to it for a week or two. The regression is not very serious from what I can see, so I think it can wait. I'll leave the needinfo on me.
Fixed by backout (see bug 1400855).
