hello, this feature will only work right if firefox is set up to keep a history of visited sites & don't delete that on shutdown in the preferences > privacy panel.

you can also add custom pages by dragging&dropping bookmarks onto the new tab page - Customize your Firefox New Tab page

Thanks madperson. My setting is correct to remember history. Its never cleared. I meant to add a screen shot before. The links work but no site thumbnail shows.

hello, sorry the i misread your first post - i thought even no pages show up. the thumbnails will also only work at the moment when disk cache is enabled (from your submitted system details it appears it is not) - please allow firefox to use at least a small amount of cache on the harddrive in preferences > advanced > network & restart the browser, then the thumbnails should regenerate when you visit the pages afterwards.

edit: in case the above does not work, enter about:config into the location bar of the browser, search for the preference named browser.cache.disk.enable and toggle it to true by double-clicking on it...

Thanks madperson that worked! Oddly enough the setting was default in the UI. I never change cache or history settings but the about:config setting was disabled. Once enabled, FF was restarted and the content started showing up after loading the pages. Thank you!
