Only applicable bug is https://bugzilla.mozilla.org/show_bug.cgi?id=1645219 . However, for the security issue involved, I think I'd prefer to use the more targeted patch in https://bugzilla.mozilla.org/show_bug.cgi?id=1642792 since the racy crash only appeared three months ago and probably can't be triggered in TenFourFox.
