Browserpass by Max Baz, Erayd

Browserpass is a browser extension for Firefox and Chrome to retrieve login details from pass (passwordstore.org) straight from your browser.

It uses native messaging to talk to a local binary that executes pass' commands to retrieve the login details in a secure manner.

Hit "Ctrl+Shift+L" to open up the password search (requires FF 53) or click the lock icon , cycle through the logins with TAB and hit ENTER to auto-fill & submit the login form of the current site.

This add-on depends on a small binary you'll need to install on your OS. Installation instructions can be found here: https://github.com/browserpass/browserpass-extension
