This is a browser extension for Mozilla Firefox and Google Chrome. It is a client for PhishDetect and it is currently capable of the following functionality:

• It regularly fetches a list of bad indicators from the configured PhishDetect Node.
• It blocks any visits to websites whose domains match a known indicator (inspired by the Blockade project).
• It integrates in various supported webmails. Everytime an email is opened it checks for known bad senders as well as known bad links inside the body.
• It modifies the links contained in the body in order to display a dialog prompt that offers the user the possibility of scanning the links with PhishDetect.
• It creates a button in the webmails' web interface to allow to share the full source email with the Node operators.
• It creates context menus and a toolbar button that allow to either send a link or directly the HTML content of the opened page to a PhishDetect backend in order to be scanned for phishing.
• It allows to scan the browsing history to identify visits to blocklisted domains.

Currently supported webmails:

• Gmail
• Roundcube
