How to make db connection windows waterfox ? App work fine just can't connect to database but firefox is fine.

Edit:
I fix it. This:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Waterfox\NativeMessagingHosts]

[HKEY_CURRENT_USER\Software\Waterfox\NativeMessagingHosts\org.keepassxc.keepassxc_browser]
@="C:\\Users\\taner\\AppData\\Local\\KeePassXC\\org.keepassxc.keepassxc_browser_tor-browser.json"


Please add offical support to waterfox.

it just doesnt work and cant figure out whats the problem. I dont have any connected database, it just writes "Key exchange was not successful." both firefox and keepassxc are portable.

A precious plugin, trivial to use (no excuse). Thanks to KeePassXC and this plugin, I can securely store all my passwords in a single container. Having a strong and different password per site / application is no more an issue. All users should use this plugin.

A la fois sûr et pratique! KeePassXC apporte la sécurité, et KeePassXC-Browser apporte une intégration agréable et pratique à Firefox. Je recommande!

funktioniert sehr gut - danke!

Browser-Independent!
KeepassXC uses open-source password file format kdbx.
Via cloud, format can easily be shared even with iOS (e.g. Strongbox).

This makes logging in much easier because you don't have to remember your username nor password. Thank you! :)

Best locally stored password manager. I highly recommend!!!

He seguido las instrucciones de instalación del plugin y del programa y las de configuración para conectarlas y... nada. La integración está habilitada, la base de datos está desbloqueada pero el plugin no ve ninguna base de datos.

Thanks you. And excuse my English, please.
I'm working with Ubuntu 18.04 and Firefox. I've read the guide and... there's no native-messaging-hosts folder neither org.keepassxc.keepassxc_browser.json file. So...
And I don't even know if this is the right place to answer.

It has helped make my digital life a little more convenient and a lot more secure. I no longer form the habit of reusing passwords because now I don't have to worry about typing out long difficult to read and remember passwords. I can just auto fill them. Thank you KeePassXC team.
