Zotero Connector Disabled

I've used Zotero for years and the connector generally functions well. But today when I mouse over the red Z on my Edge browser it keeps saying Zotero Connector is Disabled. I can't pull in data from pdfs. I've checked my extensions and I have not disabled it. It's working when I get the page icon instead of the Z icon, but then saves articles as web pages so I have to manually input the authors, etc., and manually upload the pdf. I've searched online and in this forum but can't find a solution.
