Windows, Firefox plugin: Duo 2FA prompt doesn't show


The Duo security prompt, in Windows 10, Firefox, doesn’t show, after I enter my account’s password. Just an empty background shows (please have a look at the attached screen capture). Has anyone encountered this issue ? I can’t seem to find any report of this same issue elsewhere, so I am opening this topic.

I have this issue for months now, but since I do not use much Windows it doesn’t bother me. But it would be nice to know what’s wrong and fix it.

Thank you for your help!


Hey there,
I haven’t used Duo before but I would highly recommend you to get in touch with the Bitwarden team.

Thanks! Will do.

I reached out to the Bitwarden team, and they helped me figure it out: it’s a side effect from having Cookie Autodelete and NoScript extensions. So what one can do is install Bitwarden, log in, and then only after that install the other extensions.

Hope this can be helpful for others.
