Ctrl/Cmd-shift-S on web-based pdf files
It would be nice of you could use Ctrl/Cmd-shift-S while browsing a web-based pdf file (in FF) to add the pdf file to the library. See https://forums.zotero.org/discussion/35768/pdf-import-from-url (apparently it's planned already!)
The issue is mainly what to do about adding PDFs from the connectors (i.e. Chrome/Safari)
Thanks,
