It sounds like the folder you deleted from Bookmarks was set to receive RSS feeds. Firefox is capable of receiving RSS feeds, but is not set to receive any automatically, thus reinstalling Firefox won't do anything for this situation. To bring back the folder and its automatically-updated news headlines, you'll have to go to the site where the RSS feed originated, then click the icon on the bottom status bar of Firefox. (Using the default theme, it looks like a satellite, and when mousing over it, it will say ''Add Live Bookmark for this page's feed.'') It will prompt you to select a folder...just type in ''latest headlines'' again, and save it. Then check your bookmarks and the folder should be there, with a listing of updated news from the respective site.

Hope this helps,
John
