4.1 version doesn't show tiles Rated 4 out of 5 stars
I have FF 16.0.1 and the 4.1 version of new tab tools doesn't show the tiles at all. Returned to versoin 3 and all is OKThis review is for a previous version of the add-on (4.1). This user has other reviews of this add-on.
Have you used your Firefox profile with a new version of Firefox (Aurora, Nightly etc)? You might need to clear the prefs browser.newtabpage.rows and browser.newtabpage.columns.
