hello, "latest headlines" is just a normal rss-feed - you can re-add it by visiting http://fxfeeds.mozilla.org/rss20.xml & subscribing to it using live bookmarks.

Use bookmark folders to organize your bookmarks

I am not immediately sure of the correct method of doing that, but possibly creating a new clean profile and making a note of the information would work without reinstalling, or needing to reset anything.

• What were your headlines ?
• Mine on Firefox (en-GB) are BBC
  • FEED: http://fxfeeds.mozilla.com/en-US/firefox/headlines.xml
  • SITE: http://www.bbc.co.uk/news/#sa-ns_mchannel=rss&ns_source=PublicRSS20-sa

Thanks so much!
