Is this on Linux? Do you have an example of a website where Yubikey does not work? I'm curious, because I use Firefox on Linux for years, also for work, and never hit a site where my Yubikeys would not work. (I'm also using Google Meet regularly for work from Firefox without problems)
Well, mine doesn't work, so I'm still using Chrome. When they make it work, I'll switch to Firefox. There should really be a big fat "report bug" button on all these apps that captures logs and sends it with 1-click permission and a voice recording to explain what's wrong, like Tesla FSD's bug reporting system. I don't have bandwidth to deal with their community forums and all the crap it takes to register for them.
