I have used Zotero well well for years. I purchased a new machine with Win 8 and downloaded Windows 8.1 It made all revisions to Win 8 but as usual FF (27.0.1)required a new download of Zotero. I did that. I received msg that Zotero (4.0.17) had installed successfully. But the usual ZOTERO link at bottom of browser window is no where to be seen. After repeated downloads with same result I did something stupid I tried to use the standalone version without knowing what "standalone" really means. I don't think I want standalone but some guidance would be appreciated.
