Firefox removed my Diigo toolbar. I want it back. I have been using it for years. Could you tell me how to get it back?

I went to use Firefox and I got the message that it had removed my Diigo toolbar because it could not be verified. I have been using Diigo for years. It has a lot of very important bookmarks in it. I really need it back.

Thank you for you help. Regards. Jerry Horton.

Addons that are not signed have been disabled in the latest version of Firefox for security purposes. To enable this addon again, please do the following:

  1. Type about:config in the address bar
  2. Click the I'll be careful button
  3. Locate the xpinstall.signatures.required boolean
  4. Change the value on this preference to false

Note: You may need to restart Firefox in order for the changes to take effect.

Warning: Doing the above steps may present a security threat. Please use with caution and at your own risk.

Only a temporary fix as it will not work on Firefox 44.0 and later. https://wiki.mozilla.org/Addons/Extension_Signing#Timeline
