Just updated to Sequoia 15.4 and the issue is there - click on the menu bar icon and I get the dialog to enter the verification code but no code is displayed. I uninstalled and reinstalled the firefox version of the extension and it still doesn't work.
In Edge it works as expected.
I am using Orion RC Version 0.99.132.1-rc (WebKit 621.1.2.111.4)
I am also occasionally receiving a dialog that says the extension requires Sonoma or later (screen shot attached)
