Dan,
since my post, zotero has unexpectedly begun to work correctly. No more trouble then!
But the fact is that the console error displayed a message concerning zotero : Erreur : zotero is not defined
Fichier Source : javascript:%20zotero
Ligne : 1
I hope this can help understand what went wrong?
You can download the Zotero installation file with Internet Explorer: go to www.zotero.org, right-click the download-button of the version of Zotero you want to download, and select "Save Target As...". You can then later open the downloaded .xpi-file in Firefox via either the File menu ("Open File ...") or by dragging the file into an open Firefox browser window.
