Visit http://m.ups.com/mobile/home, see no favicon , visit about:home, see no thumbnail captured, but a default globe. Even though no Favicon was found, shouldn't this page have a thumbnail generated on about:home? I see a thumbnail generated correctly in the tabs tray.  They only specify apple-touch-fullscreen and apple-touch-icon

Looking at the HTTP traffic, I see: Cache-Control: no-cache, no-store IIRC, that means we do not show a Top Site thumbnail. We still show the Tabs Tray thumbnails though. We just don't save them to disk and use them in Top Sites.
I guess that means WFM
