I use MacOS Catalina 10.15.5, Cryptomator 1.5.4, FUSE 3.10.4, latest firefox and dropbox.
When I download files directly to my Cryptomator folder - only a zero-size file is created and the download is marked as failed in firefox. I can downoad to any other folder that is not Cryptomator.
The problem only happens with this combination - it does not happen on Windows, and does not happen with any other browser on MacOS.
Any ideas what I can do?
