Zotero downloads double-clicked pdf attachements
When I double click on an item that has a pdf attachment, Firefox download a file with random name and (.pdf.part) extension. It does that every time I try to open a PDF. My download folder is full of these files.
I'm using Juris-m on Firefox for Mac with Zotfile to manage attachments (files moved to Zotfile location and linked to Zotero). Firefox is set to open PDFs with Mac Preview.
How can I stop this behavior?
But standard advice, which probably applies to Juris-M, is here: https://www.zotero.org/support/kb/file_handling_issues
