Bookmarks, history, homepage... all gone. But..

[zeldasbiggestfan]

I had to restart my computer earlier. When it came back up I clicked on my mozilla browser, and EVERYTHING is gone. My history, my bookmarks, even my homepage isn't the same. Even now as I type the "mozilla" I wrote is saying I typed it wrong with spellcheck that I had taken off.

But one thing is still here. Somehow, I came to here to test something. I was right. I'm still somehow logged into here. How is this possible, and how do I fix it?
