Downloads create zero-size file using Firefox


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?

I have the same issue since months. Something is broken.

Edit: Opened bug


I had the same issue on Windows. Not sure how it works on Mac, but updating the Dokany Library to 1.3 (uninstalled 1.2 first) with the latest Cryptomator installer fixed the issue.

See this solution in another thread:


Thanks for the info, I already saw this thread. I am on the latest FUSE (which does what Dokany does for MAC) and the problem still happens. I’ve updated FUSE a dew times and none of the updates during the months didn’t solve the issue. It is still happening.
