My hard drive was wiped clean, and I had to start over with a re-install of Mozilla on my laptop at work. I re-installed Zotero also. I can access my Zotero library from my computer at home, and while using the laptop at work I can see my library under the "My Library" tab when I log in on the zotero.org website, yet I have an "empty" new library in my Zotero pane at the foot of my Mozilla window. So it looks like my new laptop installation of Zotero in Mozilla isn't syncing to my existing library. Did I miss a step?
