I have not updated Mozilla, Windows, etc or installed add-ins. Recently I opened Mozilla and all of my current tabs were closed and I was not given the option to restore. I went into my History to try and recreate as best I could and found my History had been wiped as well. I then discovered that I cannot access my bookmarks. Online I found how to restore these but it doesn't work. I pulled up a page that I knew I'd saved and, while the bookmark star is blued out, I cannot find the bookmarks. Oddly, while my bookmarks seem to save every couple of days, the last time my backup bookmarks saved was 3/1/15. At that time, I had 1676 bookmarks! What can I say, I've been saving stuff for a very long time! Anyway, I want to be able to get these back to being available but, as I said, the restore function says it cannot restore them.

Again, I did nothing different from the time Mozilla was in full working condition until it basically wiped about everything out. Nothing. No installs, updates, etc., of any kind.
