Firefox updated iself a few days ago and I began to experience performance issues. Firefox suggested I refresh, and offered a big geen button to do this. I pressed the button and Firefox created a folder on my desk top titled Old Firefox Data. After that nothing happened. I could not restart Firefox. After three failed attempts to restart Firefox, I restarted my computer. Now Firefox works but I have no tabs, no book marks and no history. I have lost seven years accumulated links. I went to the Firefox help pages and initiated the solutions suggested only to find that the back up Firefox had left on my desk top contains no data. I can't see how to restore my links and history.
