I have updated Firefox on my computer and my Zotero library disappeared. Is it recoverable through Firefox?

more options

I have used Zotero for some time from my computer at home. My library usually appeared at the bottom of Firefox screen. I have recently updated Firefox and as the site recommended cleaned it. The letter Z in my tool bar disappeared. I also had another Zotero library that I used from my computer at work with a separate account. I have never accessed the Zotero site from my home computer. When I finished all the cleaning and restored Zotero to my tool bar and then opened the box at the bottom, the box was empty and my library was gone. I clicked the sync and the library from my office computer appeared but my library from the home computer is missing. I want to restore the library from my home computer and make it my main library. How do I do it? Does anyone have any idea?

When you say it was recommended that you clean Firefox, do you think you used the Reset feature?

One way to confirm that is to check your desktop for a folder named Old Firefox Data. Inside will be one or more semi-randomly-named folders. If you find that, your old Zotero data probably is in there, according to this article:

Moving that data SAFELY to your current Firefox profile involves several steps, so if you find the old folder, please post back for further guidance.

Or alternately, you might check with Zotero support since there are two different libraries involved and I actually don't know how you would merge those.
