Works well with a shortkey to copy and paste a login, but does not have an integration into firefox. therefore it is less convenient, but probably more secure than keepass2 = keefox:

This is the latest fork for linux. it does not require MOMO and seems to be way easier to setup and use.

Add this repo to get the latest version: https://launchpad.net/~phoerious/+archive/ubuntu/keepassxc

Older version dont work with the Firefox Plugin!

old news:

This is a c# mono implementation. Firefox and Thunderbird -Plugins exists and once it is setup, the integration works very well.

If you don't need the very latest version, just install it from debian or ubuntu repositories:

apt-get install keepass2

The debian packages are missing some dependencies to run plugins, clipboard sharing and more! so here is the list:

apt-get install mono-complete libmono-system-configuration-install4.0-cil libmono-system-management4.0-cil libmono-csharp4.0c-cil libmono-microsoft-csharp4.0-cil mono-dmcs mono-mcs xsel xdotool

IF you need the latest version, it is best to use additional repositories for an easy setup. Look here:

• https://github.com/kee-org/KeeFox/wiki/en-%7C-Installation-%7C-Linux#install-additional-plugin-dependencies-ubuntu-1604-only

You could download the .deb from packages.debian.org / sid, but it's easy to run into version conflicts between keepass2 and the KeePassRPC.plgx plugin!

The recommended repositories do not work anymore.

Manual Installation:

• Install the Kee Firefox Plugin: https://addons.mozilla.org/en-US/firefox/addon/keefox/
• Download the latest KeePassRPC.plgx release: https://github.com/kee-org/keepassrpc/releases
• Copy the KeePassRPC.plgx into the Keepass2 Plugins Directory: /usr/lib/keepass2/plugins/
• Restart Firefox and Keepass2: They should start to communicate and ask you to exchange a key code

TBD not tested, yet
