It only has offline support. On Linux the configuration is a mess. Sometimes It doesn't talk with my desktop app. Remote support should also be added, so 1 star. I also noticed this while using it: not everything is handled within the browser. When the master password is requested, It switches to the KeepassXC desktop window which makes the experience less convenient. MasterPassword could instead be entered through a small pop-up inside the browser. This is what I would have preferred.

Not able to add connected database. Nothing happens when clicking the Connect Database button. Bazzite 43 (linux) NVIDIA edition, Firefox 149, KeePassXC 2.7.12

Works fine on my Windows 10 Firefox, and in Firefox on my CachyOS Linux install.

Best password manager ever.
I know this depends of Keepassxc development, but it would be nice if card info can be stored.

Eigentlich gut, aber umständlich, funktioniert bei vielen Websites einfach mal gar nicht, das Felderkennungs-Tool zum Zuweisen ebenfalls nicht und kostet daher viel Zeit und Nerven in der Benutzung. Daher kann ich ebenso schnell und gut aus KeepassXC kopieren und einfügen und brauche mich nicht mit diesem AddOn herumschlagen; leider!

The addon randomly shows errors like "KeePassXC-Browser has encountered an error: Key exchange was not successful" which means absolutely nothing to the user and does not help solve the problem in any way. It is the same as showing a message "Error: There has been an error. You're unlucky, too bad for you."

It seems that the path for native-messaging-hosts is hardcoded.
I want to move the file located at [~/.mozilla/native-messaging-hosts/org.keepassxc.keepassxc_browser.json] to [xdg-directory :: ~/.config/mozilla], but it fails.
help me?

it doesn't work when the password is on another page after the email. it always puts the wrong password from another account without even asking which account. developers, add a dropdown to ask the user from which account to take the password, don't just put any random password from any random account in the database. changing any setting didn't fix this.
