Please help!! I use windows 8.1. After using the recovery function to a previous backup Firefox icon looked like a blank page and when I tried to open I got an error message stating that I was attempting to use an older version of Firefox which could have a problem or a virus. There were two choices, one was to exit and the other was to create new profile. Clicking on the exit did not resolve anything so I clicked on create new profile. That resulted in a new install of Firefox. I now have lost all my saved bookmarks!! How can I get them back into the new install of Firefox? Thanks. .
