Cannot download wirh Firefox

Just received my PPM and I absolutely love it!
I just don’t really like sideloading with USB/MicroSD because I would rather use the built in Browser to download files.
In some post I read that it would be possible downloading files with Firefox.
For some reason everytime I press a download link the links shows up in the bottom left corner but besides that nothing happens…
No download dialog or notification and also nothing in my local Downloads folder.
The Firefox app does not have any permissions I could grant it (I looked in the ‘hidden preferences menu’).
Unfortunetly Puffin Browser also tells me that it cannot download anything.

Any help appreciated.
Thank you in advance!
