I have set up a web page access with two-factor authentication. Using Firefox installed via Snap, I have been able to access my account. The flow is like this: The web page asks for username and password, when correctly inserted, Firefox asks me to touch my Yubikey, which lights up in that moment. I'm logged in. (The authentication method is called Yubikey U2F, if I'm not mistaken.)
Due to performance problems I have removed Firefox installed via Snap and instead installed it via apt. However, since that change I cannot authenticate on the same web page using Firefox. The page directly fails ("failed to authenticate via security key"), the Yubikey never lights up.
The same flow works flawlessly on Chrome. Reverting Firefox to Snap also re-enables U2F to work but I would like to avoid that.
System info:
- System: Ubuntu 22.04 Desktop
- I have installed libpam-u2f as recommended on yubico's documentation.
- Firefox: 107.0 from ppa:mozillateam/ppa
- Chrome: 107.0.5304.110 download from google.de/chrome
- Yubikey: 5C NFC
