User Agent: Mozilla/5.0 (X11; Linux i686; rv:21.0) Gecko/20130321 Firefox/21.0
Build ID: 20130321042014

Steps to reproduce:

Ctrl+T, Aurora 'button' > New Tab or click the ( '+' ) new tab 'button'


Actual results:

NewTab appears but only rarely does Some of the thumbs appear, others are blank squares.
I have Never had them all populate. 
~/.mozilla/ProfileName/thumbnails directory (folder) is Always empty (all nightly versions since july, 2009).. 
//chrome/browser/content/browser/newtab/newTab.js calls for 
Cu.import("resource://gre/modules/PageThumbs.jsm");
,but... there is No /modules/PageThumbs.jsm file anywhere in omin.ja



Expected results:

thumbs in NewTab should populate with a thumbnail of that page (url) on load.

i've checked other bugreports, e.g., https://bugzilla.mozilla.org/show_bug.cgi?id=726267
and have check the things mentioned in them e.g., browser.cache.disk.smart_size.enabled = false
and seem all correct (in this exp. my ..cache.disk.. is true).. 
here is another screenshot of cache entries in 'about:config'
