You shouldn't be making security decisions based on this URL.  You should be
making security decisions based on the Document's SecurityOrigin.

I have just weakened the statement in the comment. Could you take another look?

The method is used to determine whether or not to insert an extension's content
script in an about:-frames, which requires knowledge about the frame's inherited
URL:

"matches": ["http://example.com/blank/*"],
"match_about_blank": true

     // cookies. For example, if the cookie URL is http://example.com, we'll
     // use the non-Secure cookies for example.com when computing
     // document.cookie.
