SafeFrame Recommendation

Please note that the SafeFrame standard (, implemented by Flashtalking, requires modification to run on Amazon owned and operated inventory.

Flashtalking uses the following to determine a browser’s support:
if (o.safeFrame) { o.safeFrame.register(o.width, o.height); }

Our recommendation is that every method invocation use the additional check below, verifying support for that method:
if (o.safeFrame && typeof o.safeFrame.register === "function") { o.safeFrame.register(o.width, o.height); }

If this change is made, all creatives should render correctly.
