Bug 1057966 - [e10s] The help menu is blank When I open the help menu, this gets displayed in the Browser Console:

TypeError: content is null browser.js:5169

Which refers to this line:

var isPhishingPage = content.document.documentURI.startsWith("about:blocked?e=phishingBlocked");

The stack to getting there:



content is null for e10s windows, so let's just use contentAsCPOW here and see what happens, for the short-term solution.

Actually! Actually, I have a better idea. We can get the documentURI off of the browser (both remote and non-remote), spec it to a string, and do the comparison. Woo! This works.

Posting a patch.

Ok, got something posted that I like. Pushed.
