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

simple ip2location domain :

172.67.153.104 ... CloudFlare Inc.
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).
