Lost data in add-on for firefox

SibylleKuemmritz · June 25, 2017

All my references disappeared in the add-on although I did not change anything belonging to this. In my Zotero online-storage the library is still OK. The ID of this problem is: 330021609. What might be a reason for this? Please, could you help me to solve this problem? Thank you very much in advance!

What versions of Zotero and Firefox are you running?

Upgrade to Zotero 4.0.29.21. You're running an outdated version.
