Firefox took my Diigo toolbar. I want to come back. I used it for years. Could you tell me how to get it back?

I went to use Firefox and I got the message that she had taken my Diigo toolbar because it could not be verified. I've been using Diigo years. There a lot of very important bookmarks in it. I really need back.

Thank you for your help.
Kind regards.
