Chrome content script does not load in about:blank page

Question

I am developing a Chrome extension which will load content script according to the following manifest:

\"content_scripts\" : [
    {
      \"matches\" : [ \"         


        

Answer 1

Update: As of Chrome 37 (August 26, 2014), you can set the match_about_blank flagDoc to true to fire for about:blank pages.

See alib_15's answer below.

For Chrome prior to version 37:

You cannot load a Chrome content script (or userscript) on about:blank pages.

This is because about: is not one of the "permitted schemes". From chrome extensions Match Patterns:

A match pattern is essentially a URL that begins with a permitted scheme (http, https, file, ftp, or chrome-extension)...

In this case, you might be better off hijacking makewindow().

Answer 2

In the manifest file, add a line:

"content_scripts" : [
{
  "matches" : [ "<all_urls>" ],
  "match_about_blank" : true,
  "js" : [  "scripts/namespace/namespace.js",
            "scripts/log/Logger.js"]
   "run_at" : "document_start",
   "all_frames" : true
 }
