Duplicate File downloading from Firefox into Cryptomator Drive

When I download a file from Firefox (eg. an e-mail attachment) into a Cryptomator drive I end up with a duplicate file which contains the actual data, and the original file name with a 0kb file size.

eg.

MyDocument.pdf - This file is 0kB
MyDocument(1).pdf - This file contains the actual data.

Any idea what causes this and if there is a workaround / fix incoming?

I had the same issue. Updating the Dokany Library to 1.3 (uninstalled 1.2 first) with the latest Cryptomator installer fixed the issue.
