I am clicking on the link in the zotero box opened on firefox, like I always have done, and they do not open even though this is how they have always opened before. There is no error message, they just do not open.
Same problem here. Firefox updated itself this morning (to version 53.0) and since then I cannot open Zotero references in Firefox anymore. I can still open pdfs in an external viewer, but when I double click on a reference or the pdf within a reference nothing happens (where before the pdf would open up in Firefox). Right-click and 'view pdf' also does not work. Exactly like AliceAnnelin describes, there's no error message, just nothing happening.
Here it is: 325011972
But I'm going to guess that it's this: https://www.zotero.org/support/kb/files_not_syncing
See Provide Steps to Reproduce for an example of what we need.
2: I clicked on the Zotero icon in the toolbar of firefox
3: I clicked on the file I wanted
4: it did not open
Any suggestions?
