Earlier today I noticed that all my files that were placed on my desktop are now missing. I haven't changed any settings, and these files are no where to be seen in my trash and they don't appear anywhere when I search for them either. This morning Firefox also crashed on me and had to restart... it was then I realised they were missing, though I don't see how this could've impacted it. Any idea where they are or how I can recover them? Any help would be greatly appreciated.
