Document TOTALLY DISSAPEARED!!!

Document TOTALLY DISSAPEARED!!!

I just spent about 24 hours on a zoho-document, which was auto-saved (according to the browser) over and over and over. Then I closed firefox, re-opened it...and the document is completely gone. There's an old version that I started yesterday, but the new version is nowhere to be found. It's not in the trash, nothing.

I'm totally having a mental breakdown someone please tell me where I can re-find my document. I tried calling but nothing happened. I can't find it in my browser history either.
