Have you ever deleted your firefox profile?

I have.

But I was actually able to restore it.

I made a new junk profile, copied it's folder name, and deleted it. Then, I renamed my old "deleted" profile ( I had selected "dont delete files") the name of the new one, opened firefox in the "new" profile, and after I restarted firefox, FD showed up!

I had my profile back in just a few minutes.

Yeah!
