I noticed that the file /etc/udev/rules.d/70-snap.firefox.rules does not have any rules for the Trezor devices.
In my Trezor rules file, /etc/udev/rules.d/51-trezor.rules, that can be downloaded from https://data.trezor.io/udev/51-trezor.rules, I appended the FireFox snap TAG to one of the existing lines to get, for example: KERNEL=="hidraw*", ATTRS{idVendor}=="1209", ATTRS{idProduct}=="53c1", MODE="0660", GROUP="plugdev", TAG+="uaccess", TAG+="udev-acl", TAG+="snap_firefox_firefox" Unplug/replug the device and then try again in FireFox. That worked for me. So, the fix is probably for FireFox to include the Trezor U2F device configs in whatever winds up generating /etc/udev/rules.d/70-snap.firefox.rules -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1947746 Title: [Snap] Ubuntu Firefox installed from snap cannot use Trezor U2F To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1947746/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
