Download, sound and print in Firefox problems

more options

I am in another time in short time with same problems. Firefox don´t want to start any downloads. It can be small file in pdf, install files or larger files. In all cases it failed. I can not hear any sound in Firefox as printing is impossible. Exactly same operations in Edge browser working just normal. There I can dowload, listen music or hearing other sounds, as downloading is working normal.

I restored PC to early date but improvment isn´t done, so I am same trouble
