Fusion of PassLok and SynthPass
This is where you find them in the respective app stores: Chrome: https://chrome.google.com/webstore/detail/fusionkey/legnppmlegkibpinfjodjbejohblaaam Firefox: https://addons.mozilla.org/en-US/firefox/addon/fusionkey/
This is the full PassLok, not a reduced version like PassLok for Email, with all its functions. When you click the FusionKey icon with a page that is ready to add an ecrypted message or contains encrypted material, PassLok opens. If the page contains password inputs, SynthPass opens instead.
