"Error! Credentials cannot be saved or updated to a closed database."

Then open it. Prompt me for the database password. Why can the DB be opened on demand to retrieve passwords, but not to save them? I should not be expected to keep my database open all the time. That is an obvious security vulnerability. So I have it configured to close after 30 seconds. I do not understand why this Addon is so hostile to on-demand database access.

Will not work with current version of Firefox and Ubuntu 25.04. I have used this for years. Sad to see Mozilla can not keep up.

Thanks for this extension!

One remark: though firefox now honors XDG config settings in $HOME/.config/mozilla/firefox (on Linux) the extension creates a $HOME/.mozilla/native-messaging-hosts. I'd like so see all config for an application on one single place only.

Great plugin for my favorite password safe.

The add-on doesn't work in the Flatpak browser. Otherwise, I like KeePassXC :)

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.
