I installed Zotero standalone in 12.10 64bit. Some problems which I managed to fix. The one that remains is an error saying "openoffice.org could not communicate with Zotero. make sure zotero standalone or Firefox are open and set to an online state and try again".
That's when I click any button in the Zotero toolbar in libreoffice. Firefox doesn't open with a the plugin installed and a working internet connection. The Zotero troubleshooting which mentions this error was of no help to me. I find reports about this bug going back as far as 2009 but I haven't found anything of help.
