Sorry about that, and thanks for the extra details. We'll see if we can find the cause of the problem and fix it in a future version.

Ah, I think this might be caused by bug 596370: If the file you click on is automatically opened by another application, Firefox will delete it when the browser closes. If you want to save the file permanently instead of just viewing it once, you can press-and-hold on the link and choose "Save Link" instead of just tapping it.

This is a known problem with Firefox that I hope will be fixed in a future version.
