Firefox not allowing sign-in to Quicken Investments

I've just installed Firefox. I can sign-in to Quicken Investments on Chrome, but not Firefox. I get the following message "Single sign-on authentication was unsuccessful (reference # ABRNEUJV)". Also, I can sign-in to my Quicken Account fine, but not the Investments Portfolio.

    I suspect you need to unblock the tracking protection Firefox is providing.

    No, I unblocked the site in Content Blocking and it still will not load.

    Just tried it - using FF -
    - has Quicken ID signon screen
    - then rotating circle of dots
    - then the portfolio screen displayed
    Where are you getting tripped up

    As soon as I hit the sign-in button it comes up with the message I have in my initial post. I can sign-in on my IPAD using the FFox app.

    Wonder if this is related to Firefox - and Single Signon Authentication....
    as per your error message -
    and really has nothing to do with the actual Quicken website -

    I get the following message "Single sign-on authentication was unsuccessful
    How do I enable single sign on in Firefox?

    FireFox: To enable automatic Single Sign-On (SSO)

    1. In Firefox, enter about:config in the address bar.
    2. Enter negotiate in the configuration filter bar.
      The Preference Name network.negotiate-auth.trusted-uris
      should be listed.
    3. Double-Click on network.negotiate-auth.trusted-uris
      and set the value to
        ---> not sure what you should put here for Quicken
      Press OK to save the change.
    4. Close all instances of Firefox and retry access.

    Hi @Ken ,

    What version of Firefox are you using? I use Version 52.9 in my 32-Bit Builds for Windows 10, but in the 64-Bit Builds for Windows 10, I use Waterfox, based on Firefox 56.2.12 64-Bit Version. You can download it from:

    I just used Waterfox to sign into Investment Portfolio at:

    No problems. I did not have to make any adjustments for Quicken.

    Thanks everyone for trying. I did the changes ps56k suggested and it worked the first time, but not the second.
    I am using the latest version of Firefox since I only installed it a few days agol Maybe the Firefox Forum can help.

    sorry - not sure what you did to trigger this FF situation - but it is not normal...
    for either FF, or for accessing the Quicken web page
