[Bug 2062148]

[Atoyama Tokanawa]

This problem seems not to be specific to Snap. I use Firefox Nightly 128.0a1 (2024-05-19) (not snap, installed from Mozilla's tarball) and i have same problem with Hypersecu HyperFIDo device (its legacy U2F usb device).
Attempts to register new credentials on https://webauthn.io/ does not cause device to start flash lights, pushing button do nothing. Other Webauthn test sites - same result. Device is OK, since both pamu2fcfg and Chrome works just fine with it.

Searching web also shows some results from Reddit where people complain about their FIDO devices just stop working month or two ago. 
Starting fresh profile dont fix problem. Current stable version have same result.

I will try to dig it more.
