Upgrade StorageConnector stopped working
After I accidentally refreshed Firefox, Zotero Connector stopped working. I reinstalled it, but now I get an error message in Firefox that Zotero is unavailable, even though the desktop app is open. In the Zotero Connector settings, the Proxies tab is blank, and I can't access the Zotero Connector advanced settings at all.

You don't need to do anything in the Connector preferences, though — the Proxies there are totally unrelated to the system proxies discussed in the above support page.
