Pages that send a no-store or no-cache header aren't cached and thus Firefox does not generate a thumbnail.
- Bug 756881 - New tab thumbnails not displayed (or old images displayed) for Facebook, Twitter (sites using Cache-Control no-store)
but it was working at beginning for facebook or persianhub.com and some others. but one day , it became like this. i think its a problem of this feature of firefox , because they also work properly in add ons which works like this
