Since bug 57325 was fixed fast/loader/onload-willSendRequest-null-for-frame.html started failing. Our layout test controller should implement setWillSendRequestReturnsNull and not display the "Blocked access to external URL" message if this mehod is called before. Will skip the failing test for now.

Comment on attachment 87736 [details] Patch Great stuff. You should also unskip fast/loader/onload-willSendRequest-null-for-script.html, fast/loader/willSendRequest-null-for-preload.html and http/tests/misc/will-send-request-returns-null-on-redirect.html which are also skipped because of this.
I didn't finally unskip the other 3 because they need some extra stuff. Relabeled them in the Skipped file. Committed r82591
