Example URL:

Steps to reproduce the problem:
1. Set the download location to ~/.foo./
2. Try to download a file
3. Repeat with ~/.foo./bar/
4. Repeat with ~/.../
5. Repeat with ~/.../bar/

What is the expected behavior?

What went wrong?
Those download locations are very much edge cases, but they should probably work. Only ~/.foo./ and ~/.foo./bar/ work, while downloads that are sent to ~/.../ and ~/.../bar/ instantly fail with “Failed - Insufficient permissions”.

Did this work before? No

I don’t remember this ever working, but I think the failure mode was slightly different a few months ago (downloads would succeed, but merely yield empty files).
