Fóram Tacaíochta Firefox

I seem to have lost all of my bookmarks and passwords associated with my application, even though the message before I refreshed/restarted the application said that it would keep that important information, just remove things like themes and add on extensions. What do I do? I tried to go to manage bookmarks first, and under the import option, it says how many tabs were bookmarked or saves, or something, but when I go to click to restore it, it says it cannot be restored. I feel like its somewhere still there, and I really need some of that information. Any help is appreciated, thank you
