Maybe Zotero became unresponsive because it was searching through the whole database for retracted Papers which certainly took some time?
Is it possible to split the database and work with several database on one system (Mac)?
When I set "extensions.zotero.retractions.enabled" back to true, Zotero straightforward showed the retracted papers again: without restarting.
it took a bit more than 2 minutes for Zotero to show the retracted papers and becoming resposive again
It looks like it took about a second
