It's really a convenience to use this add-on with KeePassXC. But, there been an issue that has been raised several months back :

In my case
Firefox 83
KeePassXC-Browser 1.7.3
Ubuntu 20.04 LTS

`keepassxc-proxy` makes tcp connections to remote servers over internet & transfers data(with 36+ KB/s speed) without user permission under Linux root privileges.

tcp 0 0 192.168.42.245:52470 117.18.237.29:80 ESTABLISHED 20559/keepassxc-pro

209.216.230.240 .. M5 Computer Security

I tried several times, had to lock password-DB out of fear.

This bug/issue is not addressed by Firefox, claim KeePassXC team on their issue-tracker-logs.

I'm in a limbo, is Firefox breaching user privacy without their knowledge; what data is being transferred to remote servers by keepassxc-proxy?
Should I abandon Firefox; isn't it the most secure (or configurable) browser out there?
Should I change passwords of hundreds of accounts now?

I'm using AutoTyping where ever it's possible & often wished they had auto-type separately for Username & Password; you know for pages like firefox or google account logins.

cheers

This is not the first time the issues rises its head from the depths.
Here's the KeePassXC-Browser issue: https://github.com/keepassxreboot/keepassxc-browser/issues/100
And here's the Mozilla one: https://bugzilla.mozilla.org/show_bug.cgi?id=1463873

Again: this is a Firefox bug. If you look the connections keepassxc-proxy makes with Chromium-based browsers, you'll see none.

And to clarify: keepassxc-proxy does not make any connections. These are file descriptors that are leaking from the parent process (Firefox).

    I really love Keepass and have used it for years. I really wish that there was a way to link/connect it to a web browser. So far I have not found any working method to get passwords out of keepass other than copy/pasting from the program apart from on an iPhone.

    There are two ways you can get credentials out from KeePassXC: using the browser extension, or using Auto-Type. Please refer to our documention for guides: https://keepassxc.org/docs/

    "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.

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

    Actually there's already pull requests made for a websocket connection mode in both extension and KeePassXC. It works with Flatpak browsers. So it's coming :)

    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.

    The whole idea of the extension is that it talks to the desktop app. It has no direct connection to your database, and it will never ask your master password.
