On a page with <iframe sandbox="allow-scripts" src="http://test2.com/index2.html"></iframe> where the page is redirected with a 301 to another domain, there are 2 resource timing entries with the same name. This does not happen with a redirected img tag.

Comment on attachment 8421454 [details] [diff] [review] Redirected iframe inserts 2 entries into resource timing buffer Review of attachment 8421454 [details] [diff] [review]: ----------------------------------------------------------------- This patch sets the mTimingEnabled flag to false for the old channel, or else there will be 2 resources with the same name. Also passing the initiatorType from the old channel to the new one.

This only happens for the first load of the page because of bug 1009360
