Both KeepassXC and Firefox are installed via flatpak. In the KeepassXC Browser Integration tab, it sayts that it doesn’t support snap, but flatpak is not mentioned. When I try to connect to the database I got this message “Key exchange was not successful.”.
Is it possible to use KeepassXC browser extension on Firefox flatpak version?
Apparently some extra-configuration is required . See Enabling KeePassXC Add-On for Flatpak Firefox | VastActive.com
